Your child’s height, weight, and age determine how the car

Children vary widely in body size, shape, and temperament—
please consult your doctor before switching between
any modes within the limits and fit requirements of the
car seat.
State Laws
Please be certain to follow your state’s laws regarding car
seat use.
American Academy of Pediatrics
Recommendations
Infants and Toddlers
Should ride in a rear-facing car seat as long as possible, until
they reach the highest weight or height allowed by their car seat.
Toddlers and Preschoolers
Once they are facing forward, children should use a forward-
facing car seat with a harness for as long as possible, until they
reach the height and weight limits for their car seats.
School-Aged Children
Once they have outgrown their forward facing car seat, children
should use a belt-positioning booster seat until the vehicle’s
lap and shoulder seat belt fits properly. This is often when they
have reached at least 4 feet 9 inches in height and are 8 to 12
years old.
Older Children
All children younger than 13 years should be restrained in the
rear seats of vehicles for optimal protection.
Measure your child’s weight and height
(DO NOT guess) before choosing this car
seat’s mode.
