Belly to back.

George has been rolling belly to back for about two and a half months since he was three months old, but always sporadically and infrequently (which doesn't lend itself to being recorded). This morning he was rolling immediately the first three times I tried to do tummy time with him, and this is the fourth.

Way to go, buddy! Now let's work more on sitting up unassisted and just pause things after that, okay?
