My baby is 4 months 22 days old almost near to 5 months still she is not rolling over and not lifting head steadily during tummy time

A. By completing the time of three months 50% stability comes and by completing the time of six months total control of the head will be seen if you do not see that totally whether tummy time or weather in your lap then you can consult the doctor but currently you are still left with sometime you will have to wait and in case of any doubt please visit your doctor
