My ex thinks 7 is is too young to wear nail polish. I don't. I think it's fine (not for school but at other times). He wants me to never to paint her nails. I really don't see a problem. But he keeps saying he's an equal parent which he is. But so I am but I think when she's with me I can choose what is appropriate and likewise when she's with him.
Or shall I just agree with him and say no nail varnish? It just seems a ridiculous thing to argue about and you don't need nail varnish in your life.
