DD is going on holiday with my ex husband and his wife next week for 2 weeks. Her step mum is a nail technician and has said she will do acrylic nails for my daughter.
I've said no as I think she's too young (she's 14).
Ex husband says he doesn't have a problem with it and DD says I'm not being fair as her dad said it would be ok, plus her friends have had acrylics in the past.
AIBU?
