Title: Think about using them in car seats...
Review: In my childbirth class, the state car seat technician came in and explained to the class how to properly use infant car seats. She said that you shouldn't use any type of headrest that did not come with the car seat as it has not been tested and approved as safe. Instead, she recommended using rolled up receiving blankets on the sides of the baby to keep him/her from flopping over.
Is the review positive or negative?
