Lauren is really strong for such a young baby (I think). She has been able to hold up her head since birth and just continues to progress in this. She can bear her weight on both legs as long as someone keeps her steady. She likes to sit up in your lap and I just got the Bumbo back and she even enjoyed that for a time. Today I found her on her back in her crib. She had rolled over! I have discovered her like this several times, but this is the first time she managed this feat while in a calm state! Previously she was really upset and I think all the squirming sort of resulted in her rolling over. Oh - and this afternoon while in the crib, she squirmed out of her little pants! When I went to get her she was at one end of the crib and the pants were about a foot behind her little feet.
