Uhm... Mom Thats Not My Head

So last night I was showing Amy what I thought was the baby's head, considering that when they checked last Monday she was still breech. But at my doctors appointment today we found out she has turned and is head down. Yeah!!! I'm so happy and relieved that she has turned and I am no longer looking down the barrel of a C-section. The real question now is if she didn't turn while I was sleeping last night what exactly was the body part that I was showing Amy last night?
