Important Harness Adjustments
According to the American Academy of Pediatrics:
All infants should ride rear-facing until they have reached at least 1
year of age and weigh at least 20 pounds (9.1 kg). That means that
if your infant reaches 20 pounds (9.1 kg) before her first birthday, she
should remain rear-facing at least until she turns 1 year old. It is best
for children to ride rear-facing to the highest weight or height allowed
by the manufacturer.
Rear-Facing
Use rear-facing only with children:
who weigh between 5 and 35 lbs (2.3 – 15.9 kg)
•
and
the top of the child’s head is at least 1” (2.5 cm) or
•
more below the top of the child seat (Fig. A) and
the harness straps are in the nearest slots at or below
•
the child’s shoulders.
If the child cannot be secured within these requirements because the
child exceeds height or weight requirements, review the forward-facing
guidelines on page 7.
If the child cannot be secured within these requirements because the
child is too small, selection of a different child seat (such as an infant
carrier) may be required.
IMPORTANT:
See Adjusting Harness Slot Height on page 37.
