Tytan rolls from back to front!

Tuesday Tytan rolled from his back to his front...I had him under his toy while I got B's lunch ready and he was squealing and making his normal noises but they seemed to last FOREVER...anyhoo - I went to check on him and he had rolled over!!! TOO FUN!!! I can't believe he is already FOUR MONTHS OLD!!!! Exciting that he is doing more things and interacting...sad that the time is flying by so fast!!!!! He hasn't rolled over again since, but he gets excited and tries to grab his feet and rolls to his side =) SO FUN TO WATCH HIM PLAY!!! =)
