Look What I Can Do!

So all her hard work has finally paid off. A few posts ago I showed you Taylor trying to escape her crib...now she's figured out how to stand up in her crib. I went in yesterday to get her from a nap and this is how I found her! She now thinks this is what you are supposed to do when you're in the crib. She was such a good little sleeper but last night she cried when I put her down for night because she kept standing and then would either get stuck there or fall over. I also heard her crying several times at night which is unusual for her. I didn't go in as she fell asleep again fairly quickly, but I'm confident had I gone in she would have been standing up again. If only I could strap this kid down in there! Do any of you experienced parents out there have any ideas how to get her to sleep...not stand in her crib??
