My baby age is 13 months. Not yet started walking on her own. She is standing with support but not ready to walk. what's the issue please

A. But between the age of 9 to 12 months is usually learn to walk comfortably with support and 12 to 17 months is the time where we expect the child to walk independently if your child is standing and walking with support also just encourage your child to stand independently and slowly the walk will happen I think right now more of encouragement would be required
