This product didn't work for my 9 year old nail biter or my 4 year old thumb sucker. The 4 year old didn't even notice it on his nail. The 9 year old said "at first it tastes bad but then you get used to it really quick and it's not so bad anymore." I'll be spending the money for a better product next time...
