I was doing Tummy Time with Owen when he was 34 days old and he rolled over. When I put him back on his Tummy he rolled over again. I have been recording him ever since trying to get to roll over again but I haven't got him to roll over again. When he did roll over he was propped up on his arms and legs and rocking back and forth so he might have just fell over. I still count it though. I hope to get him on video rolling over sometime soon.
