Since babies are not yet big enough to use a proper seat belt, obtaining the right kind of car seat for your baby is extremely important to ensure his or her safety while traveling. Furthermore, car seats are required by law in many places for babies up to two years old.
Babies are delicate creatures, and obviously you will want to do everything you can to ensure their safety. Most baby car seats feature a five-point restraint system and are secured to the seat of the car. In the unfortunate event of a collision, they are meant to keep your baby in place.
Baby car seats should be placed in the rear seat of the vehicle whenever possible, and most of them are designed with this intention in mind. This ensures that babies will avoid being hit with passenger-side airbags, which have been shown to be harmful to babies in the past (though airbags are increasingly being designed with baby car seats in mind).
