Booster Seat Requirements
Measure your child’s weight and
height (do not guess) before
using this booster seat.
Your child’s height, weight, and age determine how
a car seat should be placed in the vehicle.
Children vary widely in body size, shape, and
temperament—please consult your doctor
before switching between any types or
modes of a car seat within the limits and fit
requirements of the seat.
Provincial Laws: Please be certain to follow your
province’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 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
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.
