What is a "convertible child safety seat"?

Stephanie Tombrello (Child Passenger Safety Educator & Executive Director, SafetyBeltSafe USA) gives expert video advice on: How do I secure my infant in a rear-facing child safety seat?; How can I secure my baby in a rear-facing seat? and more...

The second kind of rear facing seat is a convertible child safety seat that can be used rear facing and forward facing. Today in the United States, all convertible child safety seats are designed to be used to at least 3 pounds, rear facing. We want people to think about keeping their children in rear facing child safety seats for at least 18 to 24 months. But of course, if you have a convertible child safety seat, use the child safety seat rear facing as long as the child is under the poundage.
