It was bound to happen. We put her to sleep on her tummy and we walked in to find her like this. I was in denial about it and then she did it in front of me. She looks surprised when she does it- like she isn't quite sure how she ended up on her back. Baby Polly is hitting milestones. Every first for her is a mommy last for me, so it is bittersweet. Glad our little girl is growing and healthy but I love her being little.
