If using a convertible seat rear-facing for a newborn, place rolled towel around baby's head and neck for support. Never place any extra cushioning under or behind the baby. Shields are not recommended for newborns. When selecting a convertible seat for a newborn, choose one without a t-shield or tray shield in front of the baby. The shield comes up too high on the newborn and may make proper adjustment of the harness difficult.
