my baby 5 months completed still not roll over but end of the 3 rd month he roll over 3 times after that not is this problem

A. the baby will be able to roll over completely by six months of age and by 3 month only side by rolling is possible as well as complete neck holding will also come only till 6 month of age. in some children this may get delayed also but there is nothing to worry you can consult doctor for ruling out a fny other problem
