We talk to our neighbors frequently and are on a first name basis. Our toddler has now starting identifying them by first name.
I'm not sure if I should redirect him to address them as Mr. Last Name, Mr. First Name, or first name.
I would like him to have respect for adults, but at this point, the first name is all he can say. He is a late talker and doesn't pronounce most words correctly.
What are you teaching your younger toddlers?
