My 4 yr old ds has been biting his nails for about a year now and no matter how many times I tell him to stop when I catch him doing it ( which he does ) I can't seem to break the habit.
I've tried painting that varnish that tastes vile on but that does nothing and now my 18 month old dd is doing it too!
Their nails are a mess, sometimes bleeding, and I just don't know what I can do to stop it.
Please help.
