Guess Who Rolled Over!

Well, whether it was an accident or not little guy rolled over last evening!  We had him on his tummy and he kindof got upset so he was crying.  He rolled to his side which we've seen him do before.  I went out of the room for a minute came back and he was on his back.  I asked my husband if he had moved him and he hadn't.  So Isaiah did it on his own. He's only 3 weeks and a day old. I'm curious to see if he repeats his feat!  If he does this could be scary.  Hopefully he doesn't start walking at 5months or something like that! :)
