Texas law requires all children under four years old to be in a child safety seat while riding in the car. This means your baby must ride in a child safety seat when leaving the hospital. You should plan to purchase a seat that meets federal safety standards and have it installed a few weeks prior to your expected due dates.
Here are a few resources to help you with choosing and installing a child safety seat.
