My DD won't roll much and I am not sure if I should be concerned. By health nurses definitions and the norm I will probably get told she is delayed. She was born three weeks early which is not really classified as prem but due to her birth weight the paed said she was prem and actually thought maybe my dates were wrong by a week and she may have been 36 weeks. But she doesn't want to roll. She will only tolerate tummy time for five minutes. She can roll from front to back but not all the time and gets very frustrated. She won't place her hands flat or arms down to help push herself over. Today when i went to help put her arms down to help her position better to roll I heard little cracks in her shoulders. Yikes hoping I haven't broken her. But when she trys to roll she is rolling onto her shoulder which doesn't look comfortable at all. As from Back to front well she has no desire to do it. Just wondering how many others are in the same boat. She is happy to sit in front of me but not quiet at stage of propping up with pillows. She will stand and loves to stand but wont roll. It is frustrating me as I hate being told there is something wrong or your baby is slow. To me they all develop at there own speed. She is just taking much longer. I have a friends boy who has only just started walking and he was 22 months. I guess once they start rolling you cant just put in one spot and come back to them so from that perspective I am happy but I am starting to get concerned. otherwise she seems to be meeting her milestones.
