A newborn car seat is good only while your baby fits within the seat limits and the car seat has not expired, been damaged, or been involved in a crash that requires replacement.

A pumpkin seat is a nickname for an infant car seat carrier, likely because of its rounded, bucket-like shape and carry handle.

Babies do not have to use a sleep sack, but many parents choose them because they provide warmth without loose blankets in the crib.

Babies can wear thin, fitted layers in car seats, but bulky jackets should not go under the harness because they can create hidden slack.

A baby car seat cover can refer to the fabric on the seat, a weather cover, or a blanket-style cover, but anything used with a car seat should not interfere with the harness.

Bulky coats can create hidden space under the car seat harness, which may leave the straps too loose to protect your child properly in a crash.
