Car seats have come a long way when it comes to protecting children from serious, even life-threatening injuries if they are in the car when an accident occurs. Choosing the right car seat can be an overwhelming process, but the following tips can help make the right choice based on their child’s age, height and weight:nInfants and toddlers: Children should be secured in a rear-facing car seat in the back seat until they are at least two years old, or until they outgrow the height and weight limits. It is recommended that children remain in a rear-facing seat for as long as possible, because the child’s fragile neck and spinal cord are supported and protected by the car seat. Examples of rear-facing car seats include infant seats, which are only rear-facing and are designed for newborns and small babies, and convertible seats, which are full-sized car seats that can be used in the rear-facing and front-facing position, some of which may fit a newborn.
