What is the difference between performing CPR on and child versus a infant?

Well, I took a course in babysitting, and they taught us CPR for infants and children. With a child, you lay them on the ground and do a regular CPR. With infants, you lay them on your thys, with their heads twourds your knees. But if you really do want to know how to do CPR then you should take a course. I went to one at the Episcopal Academy in Newtown Square, PA. It's a summer camp, and then we recieve Red Cross certificates, indifying that we were trained by a professional.
