My 3 yr old daughter is having this very bad habit of biting her nails all the time. Actually there is no nail at all. But full time her finger will be inside her mouth. I know it is very dangerous bad habit. But i dont know how to stop her. I have scolded, beaten, advised her and i also tried to put nailpolish so that she may like it and she wont bite, i have tried putting oil. But all in vain. I have explained her what happens when she bites nails, she says dont tell that boring story again and again, i was so shocked hearing this and i dont know what to do. (She can speak very well for her age ) Please ladies advise me, did your child had this habit, what did you do. P.s. I have this habit of biting nails when i am very curious and anxious or while i watch my serials. But now bcos of her i have stopped.
