That’s what literature does, chinnychinchilla.
Read with them. Fairy tales, novels, poetry, myths, folk tales, memoirs, plays … Buy physical books (because Lord knows, there are precious few inviting libraries left) and read to them. And have them read aloud with you, every day. Don’t feel you have to stick to books aimed at any particular age group, or only read 20th /21st century fiction. 18th and 19th century novels are replete with complex emotional / domestic / political situations. As is Shakespeare. (And literature from across the world, of course.) Don’t do it for purposes of instruction, just for joy. They’ll absorb everything they’ll need for life.
A by-product of wide reading is that children discover the rights and obligations of contemporary society through their historical context.
And of course, newspapers.
( MatchaTea, we have the same tradition in our family, going back several generations. My parents have always spoken of reading the papers aloud to their parents and grandparents, long ago and very far away.)
Also - radio. Radio 4 if you’re in England. There was a thread recently where someone wanted to know how other people managed to have so much general knowledge of history, politics, culture, food … Pretty much every reply cited Radio 4, on all day, from childhood.
Having said all that, if you have teens you may find ‘Get Out of My Life, But First, Take Me and Alex Into Town’ quite helpful - for you.
