Quick FAQs
How tight does the harness need to be on my child?
Harnesses should fit snugly to provide the best protection. What is snug? There are 2 tests. The first is a pinch test. Buckle up baby and tighten the harness. Pinch a harness strap north to south, near the shoulder (there's usually more slack over the belly, so that's why you check near the shoulders). If you can pinch it, the harness isn't tight enough. The second test is a finger test. You should be able to fit only one finger (women: index finger, men: pinky finger) under the strap at the shoulder. Really, babies feel more secure when snug as a hug! Click here to learn more about correct harness use. (Source: SBS USA)
Which harness slots should I use?
Rear-facing seats: at or below shoulders (exception: Fisher Price Safe Embrace--read manual) (Source: SBS USA, Car-Safety.org) Forward-facing seats: at or above shoulders; use top slots in some seats. The top slots in some car seats are the only ones reinforced for forward-facing. The car seat manual will specify which harness slots are safe to use for forward-facing since a few seats are now available where the 2nd from top set of slots may be used for forward-facing.

How should I clean the harness straps?
Soaking the straps will remove the chemicals that make the harness fire resistant. The water won’t damage the fibers. Using detergent on the straps can weaken the harness fibers. Also, putting them in the washing machine can stretch the fibers if they get caught around the agitator. Never iron the straps to try to flatten them or use any other chemicals such as a fabric softener, bleach, starch, etc. If in doubt about how to care for the harness, use a damp wash cloth and wipe it down. A toothbrush is great for getting in the little crevices of the straps. Each car seat manual will have instructions in the last few pages telling you how to clean the straps. Caution: some harness straps cannot be removed from the car seat, so it's essential to treat them carefully. You may not be able to order a replacement set if they are ruined.

What does the chest clip do?
The chest clip, the plastic piece on the harness above the buckle, provides pre-crash positioning for the harness. It keeps the harness in the proper location on the shoulders for maximum protection. It must be positioned at armpit level to provide this protection. (Source: SBS USA)
What is EPS foam? What is EPP foam?
EPS foam, Expanded Polystyrene foam, is the foam used in bicycle helmets and picnic coolers. It is a safety device added to some car seats to protect a child's head and upper torso from impact forces by absorbing those forces. It crushes, has almost no rebound to it and is considered to be a one-impact material (Have you ever put too much ice into a styrofoam picnic cooler or broken a piece of packing styrofoam? It breaks very easily.). EPS foam is what is most commonly used in child safety seats. EPP foam, Expanded Polypropylene foam, is similar to EPS foam, but has a more elastic nature. It is currently found on the SafeGuard Child Seat, the SafeGuard Go and some Dorel child seats.
My child doesn't fit as well in the car seat with her winter coat
on. Do I need a new seat?
No, take the coat off. A fluffy winter coat will introduce slack into the harness in a crash, which could lead to ejection for the child. The fluff in the coat will compress greatly, creating "dead space." There are many polar fleece coats on the market now that are thin enough to use under a harness, yet can keep a child very warm. Land's End and LL Bean sell very warm polar fleece jackets that are relatively thin. Also, consider putting the child into the car seat, then putting the coat on backwards after she's buckled in. Or try heating a bag of rice in the microwave for a minute or so, then putting it in the car seat for a minute to warm it up. Remove it and put the child into the seat. The Cozy Rosie is a thick blanket that will keep a child safely warm in a car seat. A Car Seat Poncho is also a nice alternative and stays on the child without getting between the child and the harness. Infant seats can be covered by shower cap-style fleece covers as long as there's no padding placed behind the child in the seat as a part of the cover. Always keep extra heavy blankets in the car for everyone. (Source: SBS USA, Car-Safety.org)
I put my child in a lap-only belt in the center of the back seat. Is this
safe?
No. Lap-only belts are not safe for people. The center position of the back seat is not the safest choice if it has a lap-only belt. A lap-only belt does not provide upper body restraint, so in a frontal crash, the upper body will swing forward. Because of this lack of upper body restraint, severe, irreversible spinal cord injuries can occur as the body flies forward (commonly known as seat belt syndrome). The person's head may also strike the front seats, causing severe head injuries. Lap-only belts also do not fit young children correctly and usually lie over the soft tissues of the abdomen. A lap-only belt is preferable to no seat belt at all. Using a lap-only belt to install a harnessed car seat is just fine, assuming you can get a good fit in that position.

Many states now have booster seat laws requiring booster seats for children over age 4 and 40 lbs. It is NOT safe to use a booster seat with a lap-only belt. The booster seat may correctly position the lap-only belt over the hips, but because it boosts the child up higher, the child's head excursion (how far the head comes away from the back of the seat) will be greatly increased. E-Z-On Products and Safe Traffic System Inc. make harnesses that provide upper body restraint for use with lap-only belts. The 86-Y harness may also be used with the Ride Ryte booster seat available at E-Z-On Products. If you cannot use an E-Z-On harness or other harnessed restraint with a lap-only belt, it is safer to use the lap-only belt by itself without a booster seat. Also, check with your vehicle manufacturer to see if shoulder belts can be retrofitted in outboard positions (if you don't have them already available in those positions). Unfortunately, shoulder belts cannot be retrofitted for center seating positions. (Source: CPSafety.com, Car-Safety.org)
My car was hit yesterday in the parking lot. Do I need to replace
the car seat?
NHTSA has developed a list of guidelines regarding replacing seats after a crash: NHTSA policy on child restraint re-use. If you are unsure if the seat is safe to use, replace the seat. The insurance company of the person at fault should pay for the new seat. Call the manufacturer of the car seat; some manufacturers may send you another seat for free at their discretion. Also, your car or house insurance may cover the seat; in California, this is mandatory coverage if the seat was occupied. If you're still unsure if you should replace the seat, get a new one. It's better to be safe than sorry and car seats are far cheaper than a hospital or funeral home bill if the seat fails in the future because of the collision. Also look into getting your seat belts replaced, since they, too, will have been stressed from the impact. (Source: SBS USA)
I'm using the same car seat for my 7 month old that my 8 year old son used. I was told this isn't safe. Is that true?
It is recommended that car seats older than 5 or 6 years be replaced. Car seats 10 years or older should never be used. Why? Older seats tend to have a lot of recalls on them of which you may not be aware. Replacement parts may be unavailable. Plastic and other parts of the seat wear down and may break, especially in extreme climates. Some of this wear may not be noticeable to you. Also, technology has greatly improved the safety of newer seats and it will continue to do so. You should destroy the old seat as best you can by cutting up the straps and throwing away the shell of the seat in a black plastic bag. (Source: JPMA, SBS USA)
The sun is in my baby's eyes. What can I use to shield her face?
Sun shades that stick to the window with suction cups can become projectiles in a crash. They are not recommended, especially the roller shade type. Tinting your windows may be the best solution, but it can cost more than you're willing to spend. Prince Lionheart and Safety 1st make a vinyl tint cling that adheres to a window using static cling or you can check in the automotive section of a department store.
Can I use a body support for my baby?
No, not if it didn't come in the box with the car seat from the manufacturer; some car seats come with head supports and these car seats have been crash tested with these supports. Body supports and head and neck rolls, known as non-regulated products, are generally well-padded and used under a baby. These items can compress in a crash and leave the harness too loose on the child. A too-loose harness can lead to ejection and serious injury or death for a child. If your child needs support, buckle him into the seat first, then add rolled receiving blankets around his head and sides of his body. Nothing, except light clothing, should come between the baby, the harness and the car seat. On the other hand, if your car seat came with a head roll and you'd like to remove it, you may at any time. (Source: CPSafety.com, Car-Safety.org)
Is it safe to . . . ?
When this question is asked, the answer is generally "No" because it usually means you are asking about modifying the car seat or installation of the car seat in some manner that goes against manufacturer instructions. If you find yourself asking this question, consult your car seat manual or call the manufacturer.
Where can I find out about the laws in my state?
There are several web sites that list current state laws. You can find a link to them here.
Please remember that the laws of physics are much harsher than any state laws and many state laws are just plain laughable. It is safest to keep your child in a size-appropriate car seat for as long as possible.
What is a Child Passenger Safety Technician?
A Child Passenger Safety Technician is a person who has taken the NHTSA/Safe Kids-sponsored 3-4 day class on child passenger safety. This class teaches us all about seat belt types, crash dynamics and car seats, as well as car seat selection. A mandatory car seat checkup event is also scheduled as a part of the class. A CPS Tech must renew his/her certification every two years by obtaining continuing education units (CEUs) and participating in checkup events. Many times a CPS Tech will allow his certification to lapse, but he will continue to install seats and instruct parents. This is a dangerous practice, since an uncertified tech is not likely to be current on child passenger safety issues and it raises liability issues. Always ask if the tech helping you is current on his/her certification; a good tech will not take offense at the question at all.
Where can I find someone to check the installation of my car seat?
Look up a certified Child Passenger Safety Technician on the Safe Kids web site.
Look for a car seat checkup event here or contact your local Safe Kids coalition for their next free event: www.usa.safekids.org
What should I take when I have the installation of my car seat checked?
Take your car seat instruction manual, your vehicle instruction manual and your child. Not every tech is familiar with every car seat and vehicle, so it's wise to have manuals available. Also, we like to see how your child fits in the seat and how you buckle him/her into it. Our job is to educate you on how to use the seat properly and it's much easier to do that when the child is present. You may want to make sure you have a stroller or another adult available so you can safely put your child down while talking to the technician.
What type of seat is best for my child?
A newborn can use either an infant seat or a rear-facing convertible seat. Many convertible seats, though, don't have harness slots low enough to fit a tiny baby well, so an infant seat may be a better selection. After an infant seat is outgrown, the next step is a rear-facing convertible. It's best to use rear-facing seats to their limits.
After a rear-facing car seat, a forward-facing car seat is the next step. Either the convertible is turned forward, or a dedicated forward-facing seat (such as a combination harness/booster seat) is used to its limits. If the child is too young/immature, a higher weight harness seat can be used.
The next step is a booster seat. Studies have shown that using a high back booster with head wings protect a child better in a side impact crash than using a backless booster. A booster should be used until the 5-Step Test can be passed.
While we typically think the "best" car seat is the most expensive one, it's really the one that:
- Fits your car. You want to look for a seat that moves less than 1" when you tug on it at the belt path after it's installed. It's best to try before you buy if you can.
- Fits your child. One seat may fit your child better than another. S/he may also have preferences regarding what is comfortable.
- You can use correctly each and every ride. Look for features that are easy for you to use when the seat is installed in your vehicle. For instance, some harness adjusters work very differently when the car seat is installed in the vehicle versus just sitting on a store shelf.
You also need to find a car seat that will fit your budget. Sometimes that means the most expensive model, sometimes it means the least expensive model. The more expensive models do tend to have more user friendly features, but many expensive models cost more because of their covers (for example, the Cosco Alpha Omega 3-in-1 and Cosco Eddie Bauer 3-in-1 are the same seat, but there's a $20 price difference between the two--they used to sell a leather cover for $170 more).

Should I buy a seat with a 5-point harness or a shield?
When used properly every time, 5-point harnesses give your child the best protection. T-shields don't fit every baby and leave a lot of room between the baby and the harness. That means there's more space for your baby to move in a collision. The long stalk may also cause neck injuries, especially in smaller babies. Overhead shields get in the way of chubby tummies, chubby thighs, and heads in a collision. It's like using the dashboard as a restraint. At least one death has been attributed to an overhead shield-type car seat. Advance to page 7 of this file to see different harness types and a diagram of a car seat. (Source: SBS USA, CPSafety.com)
This car seat manual is so confusing and yet I'm supposed to read it! I'm so frustrated!
A car seat manual can be confusing with all of its warnings and cautions. Throw in all the sections on how to install the seat and most parents just toss the manual aside and "wing it". The car seat manual, however, gives you vital information. For instance, some car seats must have a certain amount of space between the car seat and the front seats; some may use a tether rear-facing, while most can't; some boosters allow the use of LATCH while in booster mode, while many don't--all of this vital information is contained in the car seat manual. How do you decode a car seat manual?
First, read all the warnings at the beginning of the manual. Next, read how your child should fit in the seat. If your child is rear-facing, read how the straps should be positioned for your car seat and adjust the straps. Do the same if your child is forward-facing. Now move onto the sections for installation. Each installation section is broken down into parts depending on how you choose to install your car seat. If you will be installing the seat rear-facing using LATCH, turn to that section. There are also sections for installing a rear-facing seat using a lap-only seat belt and a lap/shoulder seat belt. It's just a matter of choosing the method that you'll be using and reading up on it. The forward-facing section is also set up in this manner. Even though a convertible car seat manual is referred to in this example, all manuals are set up in the same manner (except for belt positioning booster seats). The final pages in the manual cover how to clean the seat and order parts. Don't forget to put the manual in a safe place so you won't lose it and can refer back to it as your child grows. Also, many manufacturers now have their manuals online.
What is a noodle?
A noodle is a styrofoam pool flotation toy. It looks like a brightly colored, 4' long cigarette and is cut to the width of the car seat and used under the foot of a rear-facing car seat to help achieve a correct recline angle. You can use up to 3 in a pyramid shape under the car seat. Nothing should be placed under a forward-facing seat. A piece of single layer rubber shelf liner is OK on slippery auto seats. (Source: SBS USA)
Lower Anchors and Tethers for CHildren is a system for installing a car seat. It is also known as ISOFIX or UAS outside of the U.S.; LATCH typically consists of 2 parts: a belt with hooks on the ends that is used in place of the vehicle's seat belts and the upper tether:
The LATCH belt goes through the appropriate belt path (rear-facing belt path for rear-facing seats, forward-facing belt path for forward-facing seats) on the car seat and the hooks connect to lower LATCH anchors in the vehicle. On car seats manufactured after September 1, 2002, this belt is permanently mounted to the car seat and should not be removed. When referring to LATCH, child passenger safety technicians usually are talking about the lower anchors and connectors. The LATCH anchors in the vehicle are found in the back seat bight (the bight is the crack between the bottom seat cushion and the back cushion), usually in outboard positions; some vehicles have a back seat large enough to have LATCH anchors in all three seating positions. Your vehicle manual will state explicitly whether you may use the lower anchors in the center back seat position: if it's not stated, it's not allowed. The car seat manual must also allow LATCH use in the center position; again, if it's not stated in the manual, it's not allowed and you must use the vehicle belt instead. Only newer vehicles are equipped with LATCH anchors in the back seat. All car seats (belt positioning booster seats, car beds and vests are exempted) manufactured after September 1, 2002, must be LATCH-compatible, though they may still use the vehicle's seat belt to be installed in non-LATCH vehicles. Check your vehicle owner's manual under the child restraint section to see if your vehicle is equipped with LATCH. The LATCH positions may also be marked with this symbol:
Another less common type of LATCH connection, called a rigid LATCH connector (used on the Baby Trend Latch-Loc base and the Jané Indy Plus booster), is a stiff bar on the car seat that snaps onto the LATCH anchors in the vehicle. The rigid LATCH connector is used in place of the belt with hooks and usually raises the cost of the car seat.
LATCH is designed to make it easier for parents and caregivers to install a car seat, but it does not make it foolproof or safer than using the vehicle's seat belt. Misuse of LATCH is occurring and there may still be compatibility problems between the car seat and the vehicle. The car seat must still be tightened down so that it moves less than 1" when you tug on it at the belt path. If you try using LATCH and the seat isn't installing tightly, try using the vehicle's seat belt instead. Do not use both the LATCH anchors and the vehicle seat belt to install the car seat. If you still can't get the seat installed correctly, you need a different car seat. For more information on LATCH, click here. For help installing a seat using LATCH, click here.

What is a tether?
A tether is a long piece of seat belt material that has a clip on the end. It is located at the top and on the back of car seats made since 1999, although many pre-1999 car seats can be retrofitted with a tether. The tether is used to secure the top of the car seat when in the forward-facing position to help keep head excursion to a minimum. Head excursion is how far a child's head will come forward from the car seat in a crash. While not necessary to use, a tether is another piece of safety equipment and should be used if at all possible. New vehicles have tether anchors already installed and most vehicles made since 1989 can have tether anchors retrofitted. The tether positions may be marked with this symbol:
Many tether anchor retrofits are easy do-it-yourself projects and instructions are often in your vehicle manual. Call your vehicle manufacturer's 800 number to get more information. If you own a Toyota, click here to see instructions for installing tether anchors. Only Britax and Sunshine Kids Radian car seats have tethers that may be used rear-facing as well. (Source: SBS USA, Car-Safety.org)
I've been hearing a lot lately about LATCH and tether anchor weight limits. What do I need to know?
Lower LATCH anchors may have weight limits of either 40 lbs. or 48 lbs.—check your vehicle owner’s manual or phone the manufacturer directly. Some vehicle manufacturers defer to the child restraint manufacturer for the weight limit on their LATCH anchors, meaning that you can use their lower anchors to the LATCH weight limit provided in the car seat manual. If the weight limit isn’t specified and you’re using a car seat with a higher harness weight than 40 lbs., err on the side of caution and discontinue the use of LATCH. Reinstall the car seat with the seat belt. Top tether anchors have weight limits of 40 lbs. or 48 lbs. generally—check your vehicle owner’s manual. Unlike lower LATCH anchors, the top tether anchor is a supplemental anchorage and you should continue to use it if you have a higher harness weight seat (see www.saferidenews.com/html/LATCH_P8.htm and www.saferidenews.com/html/LATCH_P49.htm). The top tether isn’t a main weight-bearing attachment, so using it past the vehicle manufacturer’s recommended weight limit isn’t as dangerous as using the lower LATCH anchors past their weight limits. If you are in a crash and using the tether anchor past its upper weight limit (e.g., with a higher weight limit harnessed seat), and if it does fail, it’s likely that it will only deform. It will have done it’s job of slowing down the child’s head in the first split seconds of the crash before deforming. Stop using the top tether if you are changing your combination seat to a belt positioning booster unless the directions specify otherwise.
Do I need to use the metal locking clip?
It depends. A locking clip, which is an H-shaped piece of metal, is used to lock a lap/shoulder seat belt to keep the car seat from moving. All vehicles made since 1996 have other methods of locking their seat belts, but sometimes it is preferable to use a locking clip, as in the case of a rear-facing seat that tips to one side when the seat belt is locked. Never use a locking clip with a lap-only belt. Click here for more information on locking clips. (Source: SBS USA, Safe Kids USA)
How tight is "tight enough" when installing a car seat?
A properly installed car seat will move less than 1" when you tug on it at the belt path. The vehicle's seat belts must be locked, either by their own locking mechanism or by using a locking clip. A rear-facing seat will be able to be pushed toward the back of the car if you push at the head of the seat. This is normal movement (see next question). Click here for more installation help. (Source: SBS USA, Safe Kids USA)
My rear-facing car seat can be pushed up toward the back of the car. This scares me. What can I do to stop this movement?
This movement is normal for a rear-facing car seat and is called rebounding (sometimes also called "cocooning"). In a frontal crash, the car seat will first travel down and toward the front of the vehicle. It will then rebound into the back seat before coming to a stop. There is some concern that a child can sustain facial, head and neck injuries by this movement, but these injuries are much less severe than we would see on a child who is turned forward-facing too early (before age 1 AND 20 lbs. minimum). Some car seats are available with anti-rebounding devices, such as a tether that can be used rear-facing (Britax seats), an anti-rebound bar (the the discontinued Britax Galaxy), or a base designed to not rebound (the Britax Companion and the Chicco KeyFit). As with any car seat, a properly installed car seat will lessen chances of injury: check for less than 1" of movement when you tug on it at the belt path. The vehicle's seat belts must be locked, either by its own locking mechanism or by using a locking clip. Click here for more installation help. (Source: SBS USA)
What is the safest location for the car seat in my car?
The best location for your car seat is in the middle of the back seat. If you can't get a great fit there (moves less than 1" when you tug at the belt path), then the safest place is an outboard position, assuming you can get a great fit there. If you can't get a great fit with your seat, get a new one that will be more compatible with your car (try the Interactive Compatibility Database to see what works with your car). Never, ever put a rear-facing car seat in the front seat if there's an airbag. (Source: SBS USA, Safe Kids USA)
We're having our 2nd child soon. Where should I put her rear-facing car
seat? Where should I put my son's forward-facing car seat?
A rear-facing car seat provides greater protection against frontal and side impact crashes than a forward-facing car seat. When deciding which seat to place in the center position of the back seat and which to place in the outboard position, place the seat that provides the most protection in the outboard position (the rear-facing seat). Why does a rear-facing seat provide so much protection? It rotates toward the point of impact: the back of the car seat will be between the child and the impact. In a forward-facing seat, the child rotates out of the seat toward the impact, so we like to see them in the position farthest from any impact point. If your seats won't fit closely together or your children can't be close together and you have to put both seats outboard, keep in mind that a properly restrained forward-facing child is still very well protected by the car seat. (Source: SBS USA)
Can I use the Mighty Tite to install a car seat?
It is not recommended that you use the Mighty Tite. The law governing car seat safety, FMVSS 213, does not cover after market products like the Mighty Tite. The car seat and/or the vehicle seat belt may be damaged by this device. Some manufacturers even forbid the use of this device with their car seats. Click here for more information. (Source: SBS USA, CPSafety.com)
When can I turn my baby forward-facing?
After age 1 AND 20 lbs. at the bare minimum. It is preferable to have babies rear-facing past their first birthday, since a car seat that faces the rear of the car provides the most protection in a crash. Babies' neck BONES aren't ossified, or hardened, until they are around 1 year old (1 year adjusted age for preemies). Until that time, they risk severe spinal injuries if they are forward-facing in a collision. One study found that children under age 2 are at least 4 times more likely to be injured in side impact crashes (click here). Click here to read more about why it's so important to keep babies rear-facing. (Source: SBS USA, American Academy of Pediatrics, CPSafety.com, Car-Safety.org, Crash Protection for Child Passengers)
My baby's legs touch the back seat. Is this safe?
It is just fine. There have not been any documented cases of children breaking their legs in crashes simply because their legs touched the back seat while they were rear-facing. There have been many documented cases of children breaking their necks in crashes because they were turned forward-facing too early. There have been anecdotal instances where children have broken legs in severe crashes, but it's also quite possible that severe spinal injuries could have occured in those crashes. Leg injuries heal, spinal injuries don't. In a frontal collision, the legs will fly up and away from the back seat. Click here for more information. (Source: Car-Safety.org, SBS USA, CPSafety.com)
My 5 month old is 20 lbs. I've read I should turn him forward once
he reaches that weight. Is this safe?
No. Read above about when to turn a baby forward-facing. Look for a convertible seat that can accommodate children to 33 lbs. or 35 lbs. (Source: SBS USA, American Academy of Pediatrics, CPSafety.com, Car-Safety.org, Crash Protection for Child Passengers)
But my pediatrician says that I should turn him forward, even though he's not one yet.
Your pediatrician is lacking vital information on child passenger safety and car seats. The American Academy of Pediatrics recommends that a child rear-faces until the child reaches the maximum weight and height guidelines for the rear-facing seat. A rear-facing convertible seat with a weight limit of 33 or 35 lbs. should be used if the infant seat is outgrown before the child turns 1 year old (1 year adjusted age for preemies). (Source: American Academy of Pediatrics)
When has my child outgrown a rear-facing seat?
Any rear-facing seat is outgrown when:
- The child has less than 1" of car seat above his/her head, OR
- The child has reached the maximum rear-facing weight limit of the car seat.
If an infant seat is outgrown before the child turns 1, a convertible car seat can accommodate the child rear-facing to a taller height and higher weight.
The height guidelines are put on the seat by manufacturers to give a rough number of how tall a baby can be to use the seat. Remember, a baby who is all legs can use the seat longer than a baby who has a long torso. The weight limits must be strictly followed! (Source: Car-Safety.org, SBS USA)
My rear-facing baby's head flops forward when she sleeps and she looks
uncomfortable. What can I do?
The angle for the car seat should be around 45 degrees for newborns, although the older the baby, the more upright s/he can be. A more upright seat is safer for older babies (5-6+ months) because it decreases the chance they will "ramp up" the seat in a crash. If your baby's head flops down to her chest when s/he's asleep, the angle is probably wrong. Increase the angle until 45 degrees is met, but no more than that (it's okay to guestimate). (SBS USA, Car-Safety.org)
Does the handle need to be down on an infant seat?
It depends on the manufacturer of the infant seat. Many manufacturers reinforce infant seat handles and allow them to be upright while in the vehicle; Combi even requires it for their infant seats. Because of the variation in manufacturer recommendations regarding where the infant seat handle should be positioned, it is best to consult the manual. If the manual is unclear, call the customer service line and ask. If the handle must be down and there is not enough room to put it down in your vehicle, rotate the handle down further toward the floor. In a crash, the infant seat will rebound into the back seat. If it is up, an unreinforced handle could break and seriously injure the infant or another passenger. (Source: SBS USA, Car-Safety.org)
When has my child outgrown a forward-facing seat?
Any forward-facing car seat is outgrown when:
- The tips of the child's ears are above the top of the car seat, OR
- The child's shoulders are above the top harness slots of the car seat, OR
- The child has reached the maximum forward-facing weight limit of the car seat.
The height guidelines are put on the seat by manufacturers to give a rough number of how tall a baby can be to use the seat. Remember, a baby who is all legs can use the seat longer than a baby who has a long torso. The weight limits must be strictly followed! (Source: SBS USA, Car-Safety.org, CPSafety.com)
Can my child use just the vehicle's seat belts when he's too big for the car seat?
No. The next step after a convertible or forward-facing car seat is a booster seat. Vehicle seat belts are designed for a 160 lb. adult man and will not fit a child correctly until he's around age 9 and close to 5' tall. A booster seat will boost the child up so that the lap belt will fit over his hips more safely and the shoulder belt will fit properly across his chest. Aside from the booster being the smart next step for a child, many states now have laws requiring booster use. Click here to see when your child is ready for a vehicle's seat belts. Never use a booster seat with a lap-only belt if you are not using a harness. The child could receive severe abdominal and head injuries in a crash. There are several options on the market now for bigger kids who must sit in a lap-only belt position. (Source: SBS USA, Car-Safety.org)
How do I know when my child is big enough to use the vehicle's seat belts without a booster?
SafetyBeltSafe USA has developed a simple, 5-step test:
- Does the child sit all the way back against the auto seat?
- Do the child's knees bend comfortably at the edge of the auto seat?
- Does the belt cross the shoulder between the neck and arm?
- Is the lap belt as low as possible, touching the thighs?
- Can the child stay seated like this for the whole trip?
If you answered "No" to any of the above questions, your child still needs to ride in a booster. If you forget the 5-step test, buckle yourself in a seat belt and see how it fits you. Chances are it fits low across your hips and across your shoulder and chest. The seat belt should hit all your "bony" parts and that's how it should fit your child when he passes the 5-step test.

Even if your child does pass the 5-step test, and he still fits safely in his booster seat (shoulders are at or below the shoulder belt guides, tops of ears are below the top of the headrest, and maximum weight limit hasn't been reached), you may want to consider leaving your child in the booster seat. Pelvis bones don't fully develop until around age 20. The iliac crests, the hard parts of the hips that stick out in front (and help hold the lap portion of the seat belt in place), aren't developed until a child nears the end of booster seat use or later. The arms or cutouts of a booster seat act as false hips for the child and help keep the lap portion of the seat belt in place. If your child has outgrown his booster seat and you'd like to keep him in a booster, there are larger backless models available on the market.
I put my child in a lap-only belt in the center of the back seat. Is this
safe?
No. Lap-only belts are not safe for people. The center position of the back seat is not the safest choice if it has a lap-only belt. A lap-only belt does not provide upper body restraint, so in a frontal crash, the upper body will swing forward. Because of this lack of upper body restraint, severe, irreversible spinal cord injuries can occur as the body flies forward (commonly known as seat belt syndrome). The person's head may also strike the front seats, causing severe head injuries. Lap-only belts also do not fit young children correctly and usually lie over the soft tissues of the abdomen. A lap-only belt is preferable to no seat belt at all. Using a lap-only belt to install a harnessed car seat is just fine, assuming you can get a good fit in that position.

Many states now have booster seat laws requiring booster seats for children over age 4 and 40 lbs. It is NOT safe to use a booster seat with a lap-only belt. The booster seat may correctly position the lap-only belt over the hips, but because it boosts the child up higher, the child's head excursion (how far the head comes away from the back of the seat) will be greatly increased. E-Z-On Products and Safe Traffic System Inc. make harnesses that provide upper body restraint for use with lap-only belts. The 86-Y harness may also be used with the Ride Ryte booster seat available at E-Z-On Products. If you cannot use an E-Z-On harness or other harnessed restraint with a lap-only belt, it is safer to use the lap-only belt by itself without a booster seat. Also, check with your vehicle manufacturer to see if shoulder belts can be retrofitted in outboard positions (if you don't have them already available in those positions). Unfortunately, shoulder belts cannot be retrofitted for center seating positions. (Source: CPSafety.com, Car-Safety.org)
