thump in the night

So about 6:30 this morning I heard a thump come from Madison's room. Then she started crying. So I ran in there. She was laying on her back and she smiled when she saw me. Then as I stood there, she rolled over, crawled to her bumper and proceeded to use the bumper to pull herself up the edge of the crib and stand up! And from about the chest up was sticking up out of her crib. So before her morning nap, Rick and I lowered her mattress to the lowest position. I can't believe she is crawling and pulling herself up to a stand in one week! Oh and she was so proud of herself too. Except for the fact that I thought she was going to hurt herself, it was pretty cute.
