DS has bitten his nails to his elbows. It looks sore, revolting and he can't/won't stop.
A little while ago I stupidly licked my finger after I had been cleaning with bleach and I could still taste it 2 days later. I had never tasted anything so rank.
Now if only I could find something - obviously not bleach or anything harmful - that I could use on his fingers that would stop him dead when his hand goes into his mouth... the nail bite varnish just doesn't stop him (I think he may even like the taste).
Any ideas?
