Looking for some reassurance here please. Health visitor is aware. I have a 14 month old who is not moving at all, not weight bearing on legs or pulling to sit up. She sat up at 8 months but didn’t really roll until about 10 months. In the last month she has progressed to spinning in a circle whilst sitting and if you put her on her tummy she can also spin round. This is good progress for her but obviously still far away from pulling herself up on things or weight bearing on legs. Her big sister was doing all these things by now and whilst I fully appreciate all babies are different she does seem to be falling behind. Any positive stories would be greatly appreciated.
