Hello doctor, my daughter is 15 months. She has still not started walking. She does not hold and stand at all. I try a lot but she just refuses. She immediately bends her legs and cries. What could be the reason. Any excercises to do. Please help and suggest something. That way she is very very active. Keeps kicking her Legs all the time. Don’t know I am v worried for her. Please help. Thank you.
