My Belly is Moving

I have been feeling the baby move for probably a month now. I have noticed she has been getting stronger with her movements. Monday night I laid down to go to bed and guess what, she found (what I assume to be) her feet. Always before the movements have been below or right at my belly button (which is slowly disappearing). Monday night there's movement about 3 inches above my belly button. She was doing it yesterday while I was at work and I could actually see my belly moving!
