Kids may complain about being restrained in the car, but car seats and booster seats save lives. In fact, the National Highway Traffic Safety Administration reports that using a car or booster seat in a passenger car reduces the risk of fatal injury 71 percent in children younger than 1 and 54 percent in toddlers ages 1 to 4. The statistics are just as impressive for older kids.

What type of seat should I use for my child?

Infants and toddlers should ride in rear-facing seats until they reach the highest weight or height recommended by the manufacturer. In the past, children were routinely removed from rear-facing seats when they were 2, even if they didn't meet height or weight limits. The American Academy of Pediatrics recently changed their guidelines and now recommend that kids remain in the seats as long as possible.

Toddlers and pre-schoolers who have reached the maximum height or weight limits for rear-facing seats should use forward-facing car seats. Again, the seats should be used until the child reaches the maximum height and weight recommendations.

Once kids are too tall or heavy for car seats, they will transition to booster seats. Booster seats should be used until children are 4'9" tall and 8 to 12 years old. Older children can begin using seat belts at that point but should sit in the back seat when possible, particularly if they're younger than 13.

How can I tell if the car seat is installed correctly?

Both car and booster seats should be securely fashioned with a latch system or seat belt. If the seat moves back and forth freely, it's not installed correctly. Properly installed seats should move no more than an inch in any direction.

My child's legs seem too long for the car seat. What should I do?

You may wonder if your child should move up to the next seat or a booster seat if your child's feet touch the back of car seat. As long as your child is shorter than the maximum height for the seat, he or she should remain in the current seat.

Should my child use a secondhand car seat?

Passing a seat down to your next child can be a good idea if your children are only a few years apart in age. Before you reuse a seat for a younger child, make sure that it hasn't expired or been recalled since you bought it. Throw away car and booster seats after accidents, even minor ones. The seat may look perfectly fine but may be damaged internally.

Buying secondhand car seats online or at yard sales should be avoided. You won't necessarily know if the seat has been in an accident or if it has defective latches or restraints.

Using car seats consistently, whether you're going to the grocery store or taking a cross-country trip, can help your child avoid serious injuries due to traffic accidents. Talk to your child's pediatrician if you have questions about the seats.
