Hi My baby is 5month 15 days old and still not has started rolling over . is it normal or not? Another she has started sitting with support but i want to know till when she can sit on her own?

Hi See, do not get worked up by all such things and do not compare children's growth. All children have different developmental milestones. They reach these milestones at their own body pace. So it is perfectly normal if your one child has started sitting and other is still not started. He will eventually start rolling and may be he would not and straight away starts sitting. Please relax and watch them grow. Yes, if he doesn't sit at all on his own in a couple of months then consult your doctor.
