During dinner last night I looked over to see Mr. Blake rolled on to his side! I am not sure when that is supposed to happen, but it took me by suprise. He was looking into the mirror on the play gym. I think it may have to do with him not liking to turn his head to the right - the direction to which to mirror was. I suppose he decided that rolling was easier for him. Maybe it was a fluke - the boy has some strong legs - but I thought it was pretty neat!
