my son as well as daughter have habit of biting nails and some times eating her nosy. how to make them stop it? I have tried everything telling politely, shouting , giving warning..nothing works

A. Regular counselling is going to be very helpful a lot of kids do it because it is a genetic habit to bite their nails actually a lot of infections by constantly doing it and also it looks so bad and the kids are also eating buggies how a lot of kids do that but you have to tell them how unhygienic and dirty it is
