Big kid tricks

So apparently E can roll over from his back to his stomach. We have never witnessed him do this yet...but we have walked in to find him on his stomach 3 times now in the morning after we put him to sleep on his back. Since the first month we have witnessed him roll from his tummy to his back (it might have been an accident bc he couldn't hold himself up) but never the other way. Can't wait to catch him in action sometime soon :)
