Rolling Over

Last week I decided that I needed to get some type of mat to put on the floor for Dietrich to have daily tummy time on. We found the perfect one made by Fisher-Price that is an overhead gym when he is on his back, then the toys transfer to the floor for tummy time and it even converts to a tunnel once he can crawl. So I put him on his tummy today and was taking pictures of him. I looked away and when I looked back he was on his back!!! I put him back on his tummy after calling Steve over, and we saw him extend his left arm and roll himself over on to his back. I put him on his tummy again and got it on video! I didn't think he was supposed to be rolling over at 3 months. I guess I have to watch him a lot more carefully now when he's on the couch!!
