Why Do Car Seats Have Expiration Dates: Complete Guide

For safety and optimum quality, foods have expiration dates, and drugs and medications have expiration dates to prevent using weakening or other unsafe changes. Even shampoos and toothpaste have expiration dates. Did you realize that children’s car seats have expiration dates, too? If you have been out of the baby business for several years, or are just getting to that phase of life, you may not have given this any thought or even know that is the case.


Back in the 60’s a “car seat” was basically the equivalent of a plastic ice cream tub with wire coat hanger legs that cost between $5 and $7 at the local five and dime. The plastic part was thin – you could see light through it. It was vented down the back to allow air circulation, though little good that did because the seats were lined with a plastic covered foam pad “for comfort.” There was a little handle cut out at the top for easy carrying, and a 1-inch wide plastic strap around the waist was supposed to keep the little one contained. An adjustable wire stand beneath the seat (which was just snapped into a couple of tabs, by the way) could sit your little one up or down in any of three or four positions. The entire seat weighed about two pounds, could be rinsed in the tub, and was often seen being held together by masking or duct tape after being used for a couple of kids.


Not only were these seats lightweight, but they were also much less bulky than the seats of today and would fit just about anywhere. People put them on the floor of the car, sideways on a seat, or in their lap. Most people didn’t even bother to strap them to the seat, and they were usually placed up front by Daddy and Mommy, so the ride would not have to be interrupted if nursing or diaper changing was necessary during the drive. Horrified yet?


Car seats have come a long way since then. Heavy molded plastic seats have multiple slots to fit seat belts through. The angle the baby sits at is adjustable. The seats are padded an inch or so thick in soft and washable fabrics for optimum comfort and breathability. There are head rests and foot rests and cup holders. There are more generic brands and designer brands, and all in a rainbow of colors. You can get units as one-piece dedicated car seats, or they detach from the base and can be carried indoors or placed in a stroller. Those are a lot of great features, and they seem to be made well enough to last through a few kids, so why do car seats have expiration dates?

Who Needs to Understand Car Seat Expiration and Laws?

Anyone who is a parent, grandparent, babysitter or another type of child caretaker needs to be aware of, and understand, car seat expiration dates and the laws that go with using them. Are the expiration dates just a gimmick by a bunch of lobbyists forcing people to replace an expensive item for the benefit of the manufacturers? Truthfully, there are real and legitimate reasons why a car seat can become unsafe within a six-to-ten-year period.

Where Do You Find the Expiration Date on a car seat?

Look at the tag or label on the bottom of the seat, and the expiration date should be printed there, but it is also required to be imprinted in the plastic itself in order to avoid someone switching the labels on a seat. There is also a height and weight guideline printed there.

What are the Laws for Using Baby Car Seats?

The laws regulating the use of your car seat may vary from state to state. Just because you can allow your preschool age child to ride without a car seat in one state doesn’t mean that is the case across the border, and please use common sense. A preschooler will at the very least require a booster seat. Check your state’s laws if you will have any children up to age 8 in your vehicle, and since state laws vary, here is a summary of the guidelines given by the American Academy of Pediatrics for an idea of rules to follow. One of their main focuses is that a baby, infant or young toddler is much less likely to suffer head, neck or spinal cord injuries in a rear-facing seat due to the increased support.

1. Pay attention to the weight limit of each car seat. Realize that although a seat may be safe for a 10-poundto 30-pound infant, your two-year-old is not likely to do well sitting in it.


2. Babies and infants must be rear-facing until they are two-years-old or outgrow the height and weight recommendations of the seat.


3. At two years of age, or sooner if they have surpassed the recommended limits, the child can sit forward-facing provided they are in a car seat with harness straps until they reach the recommended height and weight limits (65-pounds to 80-pounds) of the larger seat.


4. Sitting on the back seat of the car with a seat belt is not allowed until they reach the established weight and height limits and they should still be buckled into a belt-positioning booster seat at that point.


5. Children less than 13 years old still need to be sitting in the back but must use a lap belt and shoulder restraint in order to be safe. Once a child reaches 13 years old, they may sit in the front seat, but only with seat and shoulder restraints buckled snuggly in place.

It is also recommended that you do not purchase a used or secondhand car seat as you do not know how it was taken care of or what problems it may have – even if it is still within the expiration date. However, if you have a good seat that has been well cared for, you no longer need it and there is time left on it, take it to your local family shelter or police station. They can inspect it and approve it for re-use by those in need.

Not sure which car seat is right for your little one? The American Academy of Pediatrics has an app to help educate you and assist you in making a good choice. For those who cannot afford a quality car seat for financial reasons or the child is unable to ride in a standard car seat for medical reasons, there is also a car seat loaner program.


If you have ever asked yourself “why do car seats have expiration dates?” you are not alone but knowing will help your make a wise decision on behalf of your precious little ones and that secure feeling doesn’t need an expiration date.
