my son is 15 months old now..he is not walking independently yet. is it normal? he walks nicely with support

A. You are still left two more months by the time of 17 we expect the child to walk on its own so right now you should just try and encourage your child make your child walk with your support in between and area whether there is no support leave the child there and just go a little far like 10 steps and encourage your child to walk towards You this is going to be a good practice
