The thought just popped into my head! Maybe this is something that does have a word or will!
It seems like more and more there is a move for gender neutrality in language and also a lot of people claiming gender fluidity and being offended by pronouns. Sooooo if they have children what do the children call them?!
mum and dad are out of the question, it's too "sexed up". So is there an affectionate name for "parent"?
