It’s tricky to make sure everyone feels included sometimes. Here are some non-binary terms for everyday use.
For a mixed group of people
Folks (see also, Folx)
People (see also Peeps)
Foolish Mortals, Rat Bags, Noodles, You Horrible Lot, Hominids [these are all to be said in a nice way, and as a joke, just so you know…]
Children: class, weans, kids, kiddies, wee-ones, possums, lambs, loves, my loves, campers.
Offspring, Siblings, Niblings (your sibling’s children), My oldest/youngest, My nibling, Parents, Family, Grandparent, Nuncle (goes with nibling and probably better than nunty?)
For a person of any gender
Mate, Pet, My lovely, Duckie, Honeybun, Chicken-poodle, Lambie,
Doctor, Professor, Judge, the Right Honourable, Bishop, the Reverend, Very Reverend
Your highness, oh Great One, Mighty Ruler, Wonderful Counsellor, Your Grace, the Everlasting [these will usually be sarcastic?]
