I checked her out when I got home and she had a tiny scratch/bump on her head but it was gone within the hour. I can't imagine how scary it must have been if she had toppled out of her crib while reaching for something. My husband wondered if she climbed out. I have no clue.
It sounds like we have a little escape artist on our hands. It's scary and silly at the same time. She cracks me up. We'll be lowering the crib to the very bottom in hopes this doesn't happen again anytime in the near future.
