Why Not Use Car Seats as Baby Chairs?
Many parents use car seats to hold babies when not in the car. But car seats are not designed for this. Using them too long can be unsafe.
Babies need different places to sit and move. Spending too much time in car seats may slow their muscle growth. It also limits their natural movement.
When Should Babies Stop Using Rear-Facing Car Seats?
Babies should stay rear-facing as long as possible. Experts say until at least age 2. Rear-facing seats protect babies better in accidents.
