Rear-Facing Infant Seat
-Make sure your car seat base is installed at the correct recline angle. Babies must ride sitting semi-reclined so their airways remain open. Most infant car seats have built in angle indicators to assist you.
-Properly position the harness on your child. Harness straps should lie flat, not twisted. They should be placed through the slots located at or below your child's shoulders.
-The harness is snug enough when you cannot pinch any extra strap material at the shoulder.
-Place the chest clip at the armpit level.
RULE:
Parents must keep toddlers in rear-facing car seats until age 2, or until they reach the maximum height and weight listed for their given car seat model.
Forward-Facing Car Seats
-Properly position the harness on your child. Harness straps should lie flat, not twisted. They should be placed through the slots located at or above your child's shoulders.
-Buckle the harness and the chest clip, then tighten. The harness is snug enough when you cannot pinch any extra strap material at the shoulder.
-Place the chest clip at armpit level.
RULE: Once forward-facing, children should be buckled in a five-point harness car seat system until they either reach age 4 or weigh 40 pounds, whichever comes first.
Booster Seat
-Have your child sit in the seat and then fasten the seat belt.
-Position the lap/shoulder belt on your child; correctly positioning the lap belt across his/her upper thighs and the shoulder belt across his/her chest.
RULE: Most children will need to ride in a belt-positioning booster seat until they have reached 4 feet 9 inches tall and are between 8 and 12 years of age.
