Jack rolled over for the first time on the day he turned one month old. Both Jonathan and I were there to see it and it was cool but honestly I thought it was just a random thing. I didn't expect him to do it again until he was about 3 months old. Clearly Jack had other plans. Now I put him on his tummy and he refuses to stay there long. He repeatedly rolls over every time. I have a feeling we may have our hands full with this one!
