my baby is 4 month 17 days now but till now she is not rolling and her head is not steady also. she was hospitalized for 1.5 month when she was 1 month old. should i worry or should i wait?

A. There are two things in this thing I’d like to tell you First is that the child can learn to roll over between the time of three months to 9 months so practically there is no delay in that and the head is partially stable partially then there is no problem but if you feel there a delay in the growth of your child and yes you should visit your doctor
