My baby is almost 7 months old (on the 10th) and has ZERO interest in rolling over. He has a lot of floor time and I’m really not sure what to do. His head is still pretty flat and I know rolling over will probably help with that but I can’t seam to get him to do it. He rolls belly to back but doesn’t care about rolling from back to belly. He’ll go from the sitting position to rolling onto his belly but that’s about it.
