The first step is to have your baby’s car seat reclined to a proper angle. Secondly, harness the snug straps to secure the body from each side, and the head will remain in position. Third, set the chest plate at the armpits’ level. And last, make sure there is no gap between the baby’s bottom and the snug crotch buckle to keep the baby from slouching. If the baby slouches, the head may lie on the chest, blocking the airway.
