my son is 4 yrs old still no listening to our instructions

A. Is your child responding when you call out the name also because if the child is not even doing that that means there’s a delay in the growth of your child mentally the child is unable to understand these things it’s very important for you to have an assessment with a child psychologist they have to examine and read the behaviour of the child and accordingly they can guide you and also also I will suggest you anything is positive in what I am saying then please start with the homoeopathic treatment as well
