There are two styles of baby's car seats, and these are; rear-facing and forward-facing. All babies should be rear-facing until they reach the age of 15 months. At this age, your baby's neck is not strong enough to withstand pressure from a head-on collision if facing forward
After this stage, your baby can use a forward-facing seat until the age of 4. The seat should have an integral harness to put the baby infirm, comfortable, and safe position
