There are several types of car seats designed for different stages of a child's growth: - Infant Car Seats: Suitable for newborns and small babies, these are always rear-facing. - Convertible Car Seats: These can be used as both rear-facing and forward-facing seats, making them versatile as the child grows. - Booster Seats: For older children who have outgrown forward-facing car seats but are not yet big enough for seat belts alone.
