Baby-Proofing a Little Higher

So we knew that if we stood her up in the playpen she could stay standing. This is a pic of her watching TV (Planet Earth, of course) and snacking on the playpen pad.
Then, the other day she decided that the bottom shelf was not good enough... I guess the view wasn't good enough this way because... This last pic is after da-da-da got worried and put a few blankets behind her. It was a great idea, because 2 minutes later she let go. As we have already found out, our hardwood floor is not kind to little heads during a fall.
