My son bites his finger and toe nails...I have to watch him because he will also bite the skin around them until it bleeds...his psychiatrist suggested getting "bitter nail polish"..you can get it at walgreens...I am going to get it soon...

My so is 3 i tried the nail polish from walgreens but it didnt work. I wonder what i can do

Try putting drop of hot sauce I know its mean but thats how my mom got oil brother from biting himself when was little
