DD14 has always bitten her nails but recently went to get her nails done because 'everyone does'- because they were so short she had false ones stuck on but they actually looked very nice.Her own nails have had a chance to grow underneath.DH disagrees , he says she's too young and we had an argument about it.In fact generally he thinks I'm not strict enough and it's starting to cause problems between us! I'd like to hear what other people think.
