I left Maddie on the floor today playing with some toys on her tummy and went to the fridge to grab some yogurt. When I came back to the living room, there she was on her back! I put her back on her tummy and after a few minutes she had managed to roll over onto her back again.
I know I said she had rolled over before, but it was always when I was playing with her, trying to show her how. This was definitely unassisted and uncoached. Yay - milestone day!
