Child Development Quiz

Children are usually big enough to use a regular seat when they are 8 to 12 years old. But children ages 12 and younger should ride in the back seat. Before letting your children use the regular seat and adult seat belt, make sure the seat belts fit them. The shoulder belt should lie across the chest, not the neck or throat, says the American Academy of Pediatrics (AAP). The lap belt should lie across the thighs, not the stomach. Children should be big enough to sit so that their back is against the back of the seat and their feet are hanging down, with the knees bent. Until your child reaches this size, they should stay in a booster seat.

Call your child's provider right away if your child has fallen or taken a blow to the head and briefly lost consciousness, is acting strangely, or is vomiting. Get emergency medical care after a fall or blow to the head if your child is unconscious; is breathing abnormally; is bleeding from the mouth, nose or ear; has pupils of unequal size; or is dizzy or confused.
