My Almost 3Y/o Won't Keep Her Hands Out of Her Mouth or Nose!

My daughter is 6 and still bites her fingers and nails. The doctor told me it was a nervous habit, but told me to get THUM from the pharmacy (Sally's has their verson too)and put it on her fingers. It's like a peppery nail polish and it seems to work when I remember to put it on. I've also given her things to carry, like a purse or a book, so that her hands are busy doing something else. Now I only notice it when she is really nervous, like during soccer games. It drives me crazy and drawing attention to it only seems to make it worse. I was also told to try having her chew gum to keep her mouth busy with something else, but my daughter doesn't like gum so that didn't work for us.
Good luck!

My 3 yr old also bites his nails and even tears at his toenails. So I will happy to see any suggestions! Sorry I was of no help!!

With three other kids part of this suggestion won't be easy, but try & pay extra attention, read a story, make a big deal out of putting polish on her nails, and I've heard of putting stuff on thier fingers that taste bad, so if she subconsciously did it, she would take it right back out.

I did not respond, but it says I did.??????
