Buying a Car Seat Make sure the seat conforms to national standards. Buy the seat that is right for your child.
Children outgrow car seats just like they outgrow shoes.
And, like shoes, car seats must fit properly to be effective. Infant car seats are designed to protect your baby's fragile neck and head during a crash. Resist the temptation to save money by purchasing a car seat advertised as being able to accommodate infants and children weighing from 20 to 40 pounds. Such seats don't adequately protect infants. They can slide around inside them, and the seats often don't tilt enough to protect a baby's neck.
