Our (almost) 4-year-old calls my friends by their first name. I've been wondering if instead, we should encourage him to call them "Uncle Firstname" or "Aunt Firstname". Or alternatively, "Mr. Firstname" or "Mrs. Firstname".

I don't love either option though... I guess the only reason I've considered them is that it feels weird to me to have toddlers address adults by their first name! In the grand scheme of life none of this really matters, but I thought I'd ask how you guys handle friends' names and your LO.

Does your LO call your friends "uncle/aunt"? Mr./Mrs.? Something else entirely?
