I missed it!!

A few weeks ago I put Bella on her tummy to play. I walked out of the room for a minute to talk to Jacob and Chloe and when I walked back in she was on her back!!! I can't believe I missed it!! Fortunately, I have since seen her roll over. She is also able to sit up on her own. Of course sometimes when she starts grabbing for toys she will fall over. I can't believe how big she is getting. She wiil be 6 months on Saturday.
