My baby is 12 months old. when she will stand up and walk without any support and how I help her. please guide me

A. Somewhere between the age of 10 to 12 months or you can say 9 to 12 months a child would learn to walk with support and somewhere between the age of 12 to 17 months a child can learn to walk independently so try to encourage your child to work with support and then independently over the period
