Last night I pulled out the kids' baby books to look up some of their "firsts." I noticed they had all rolled over by about four months and wondered when Oliver would. I remembered his doctor saying that he might do things later because he was so big and it's harder to roll over, sit up, walk, and so on. Well, I guess Oliver didn't want to be outdone by his brothers and sisters because today he rolled over for the first (and second) time!
I had put him down on his play mat while I cleaned up the kitchen and when I glanced over he was struggling with all his might to roll over.
