Infant car seats are not only the smart way to transport your child, but in most states they are required by law. These seats are designed to maximize the protection of an infant should they be in the car during an accident. Car seats are generally expensive, but the safety of the child makes them worth the expense.
Infant car seats should always be of the rear-facing variety. Car seats that face the back of the vehicle offer the best possible protection from whiplash and other injuries common to a car crash. Proper head/neck support as well as side impact protection should be included in a quality baby car seat.
Infant car seats should not be used once the child has outgrown, even if just slightly. These seats are generally only designed to protect infants under a certain height and weight. Once your child outgrows their infant seat, toddler seats are recommended.
