Water magic

Addison is 9 months old now and is still not really crawling. The doctor assures us that this is fine, but we have been really trying to get her to crawl. Also, she has started pulling herself up on one knee and one foot, but she can't seem to pull herself all the way up on two feet. Tonight during her bath she both crawled and pulled herself up all the way onto two feet.
I think the reason she crawled is because she wanted to get to a toy at the other end of the bathtub and she knew she had to keep her head above the water. She normally just lays on her stomach and pulls herself to where she wants to go or she rolls to where she wants to go. But when there is water and she knows she can not lay down, she crawls. Now if only she would try doing it out of water.
As for why she was able to pull herself up onto two feet, I don't really know. It might have something to do with the fact that the side of the tub is lower then the other surfaces she has been using to try to pull herself up with. I really don't know. But I think it is very funny that it takes water to make her do things we have been trying to get her to do for months.
