Don't get too excited we are not rolling over yet.
We are working on it, with little effort because that is how we roll (get it?)
When I took Mason for his 4 month check up the doctor asked me if he was rolling yet. My response was "rolling? Ha is hasn't even attempted to do that." Apparently that was the wrong response. She informed me that he should have been doing that by now or at least trying. I wasn't too concerned that he he had not reached this milestone yet, he will when he is ready, but I have been spending more time on the floor with him rolling him from side to side hoping he will get the hang of it
I try holding and placing toys just out of reach and guiding him to get them. Usually he just lays there and flops whichever way he falls once I let him go.
