Tips
For proper protection, an infant must
ride in a reclined, or semi-reclined
position. To determine the proper
reclining angle, check with the baby's
doctor or follow the seat maker's
recommendations.
To achieve the desired reclining
angle, it may help to put a rolled up
towel under the toe of the child seat,
as shown.
