Last week Spencer turned 3 months old, and apparently he decided that it was time for him to learn how to roll over. He worked on it all week, and by the 21st had gotten all the way over from back to front. Now whenever we put him down on his back, he almost immediately rolls over to his tummy. Needless to say, we are very impressed.
Here is a little video with several attempts. I apologize for the poor quality and large size. I am still trying to figure out how best to share video on the internet.
