My daughter is a closet roller!

She rolled over today again. Twice. And I missed it again. Twice! I swear, it's almost as if she didn't want me to see her do it. I turned my back to her for a couple of minutes, looked around, and bam! she's on her tummy! When I'm looking at her, she giggles and looks back at me and absolutely refuses to roll over! And she only does it in her crib; when I put her on the floor in the living room, she seems to forget how to roll... Oh well, I'll catch her one day, even if it means I have to sit by her crib, hiding behind the crib bumper so that she doesn't see me, lol.
