I always have done it and worse when wound up etc.
To the point they bleed., from cuticle to tip they are 1cm.so very unsightly and yuk
Tried the varnish, fouls tasting stuff. Fidnt work. And would want to use now because of touching the babys items.
I'm getting married next year so I need them to be nice.. Each day I try to stop, my brain thinks ah one more day wont hurt.. Like starting a diet lol

And above all else. Its a horrible disgusting vile habit..
