A. Your first first you to ask your child what is the problem and it’s not that it doesn’t come here if you sit there properly it will come so it’s only about counselling now and you cannot actually let the child because it’s very unhealthy unhygienic and dirty to clean and under pant for a 4year old you have to make your child understand these things because only counselling is going to help there is no other way you have tried everything
