Look what I can do!

We have been trying to have Blair sit up unassisted for a while now. She has been able to sit for just a few seconds by herself for a few weeks now. Last night, we tried again and she sat nice and upright for probably about 3 or 4 minutes before falling over. Now that Blair knows that she can sit up, she does not want to lay on her back or tummy. I'm sure that before long, she will be crawling... She is growing up too fast!
