Baby M rolled over for the first time yesterday, and we all missed it! I put him in his crib last night lying on his back, and this morning I found him on his stomach. He's been shifting his whole body to one side for the past week, so I knew that any day now, he'd be able to flip over; I just didn't think he'd do it in the middle of the night. In addition to rolling over to his stomach, he also turned 180 degrees around in the crib, facing the other way when I went to pick him up. Baby M is so active... no doubt we will have our hands full once he gets mobile!
