my daughter is 3 yrs and 3 months and has developed a habit of nail biting. I have many a time asked her not to do but still she does it. what could be the reason and what to do so that she will not do it

A. Femite lotion you can apply to so bad in taste that the child is eventually going to give up on this habit second thing it could be associated with some genetic issues that kids have like into its genetics also second a child can be low and confidence or is an introvert child that can also be associated with that and sometimes if the child has some kind of fear that a child can behave like this
