Is a car seat necessary for a 4-month-old on long drives?

A car seat is absolutely essential for your baby's safety during any car journey, regardless of the distance. While some parents worry about the baby's posture, modern car seats are designed to support an infant's spine if used correctly. For long drives, plan to take breaks every 60 to 90 minutes to allow the baby to stretch, and if they become fussy, pull over safely to soothe them before resuming the trip.
