DP's girls are 5&2.
They routinely wear coloured nail varnish. He doesn't like this and thinks they are too young for nail varnish and make up but his exw says its 'girls bonding' for them to all do make up and nails together and she really enjoys it as an activity for them to do.
I have said that he can voice his opinion as their father but ultimately while they're in exw house it's up to her what goes on. However I think it's entirely reasonable for him to say 'no nail varnish and make up' when they are with him. His ex is doing the whole " mummy lets you but daddy and allnew won't, they're so mean" with them. She tells him we are being far too over the top and because I don't have DDs I don't understand that little girls want to do nails and make up.
AIBU to not allow nail varnish and make up when they're in our home?
