Rolling over...back to front!

So Michelle is hanging out on her activity mat, on her back, kicking and grabbing at her mobiles. I go into the office to check email, Barry hits the bathroom. I go back out to find Michelle, head held high, on her tummy propped on up on elbows. "Barry! Did you put Michelle on her tummy?" I call out. "No! She must have rolled over by herself." Apparently so! Another milestone met and we were both here to see it. And THIS is why I can't possibly go back to work right now.
