What do you call your teen?

When speaking to them? Their name. When speaking about them? Usually “my kiddo”

All three of those

When I say “kid” to my kiddo i think of Indiana Jones and ShortRound 🥰

If speaking about them to those that don't know me/ them well I will say "My Son/ daughter"
To them, it's their real full name or nickname

By his name or I say mate which is slang for friend in the uk

interesting.

Buddy

aww that's a cute one.
