stop biting their nails

I've been a nail bitter for as long as I can remember. My brother also bites his nails, but has mostly broken the habit. I've always believed I picked up this habit from my Dad, as he was a nail bitter also, but I don't remember how I learned the habit. I try not to bite my nails around my kids and thus far, they haven't gotten into the habit. Your kids will pick up some of your habits, both good and bad. There can be many causes though, including stress (new school, etc), so it's probably best to talk to your doctor about it.
