Sorry if this has been covered in depth elsewhere - I've tried a "search" but it's not working for me just now ...
My dd (6) and ds (4) both bite their finger nails. Any one got any ideas for breaking this habit? I've never done it myself so I'm a bit lost. Maybe it's hereditary, dh is constantly picking at his fingers and gnawing them (although he doesn't bite his nails). It drives me MAD!
