Have you ever known a doctor to encourage giving Benadryl to get your child to sleep? Normally they say not to so I was surprised to find out that my child's doctor encouraged it. He's a little guy and needs to have a CT scan done. They made the appointment for bright and early in the morning so we have to wake him and then give him meds to "knock him out" because she doesn't really want to give him anesthetics. What is your take on this?
