hi doctor . my baby is 9 months 15days old .. she is very active n having food properly.. she got 4 teeth too... she is rolling n moving forward fastly by her tummy .. but she is not sitting her own .. is it normal ?? I'm just worried

A. Childhood mostly not to sit by this time we expect the child to learn to sit independently by the time of 8 to 8 1/2 months so currently in the situation I would one time recommended to have a proper assessment with your doctor for better clarity
