Query: Excellent for newborns

I agree with the other reviewers who commented that directions would be helpful and should be included, but it doesn't take a degree in rocket science to figure out how to "install" the headrest. Once hooked in, it stays in place and I have never had to re-adjust it. You must put both headrests in to secure it for a newborn's head.The headrest is great ... it keeps my newborn son's head stationary & from rolling around in his infant seat. Our infant seat goes in the car and in a jogging stroller and I've had success with both.
