AIBU to be upset about what 3yo has said

[happymommaof2]

DS, 3 years old was picked up from Nursery by his dad's gf last night. She has text me this morning to say he called her a fat fuck in the car when she picked him up! I am absolutely gutted. I am 100% certain he has not heard it at my house and 98% certain he hasn't heard it at his dads. She said he was really upset about getting in trouble and it was clear he had no idea what he was saying.

Just the thought of those horrible words coming out of his little mouth - the best insult he can normally muster is "I'm not your best friend!"

I have phoned nursery to make them aware, I really don't want them to think he is that kind of child :(

New swear word: ninja??????

halfwitpicker when DD was 2, she shouted at me, "I'm not putting the toys in the damn crate!" 😂

When my ds was small he got confused between "kerb" and "Kent" (the name of the lane) and said cunt it took months for me to convince him that kerb and Kent were OK words but cunt wasn't. Even now sometimes he stops himself and asks which K word is the correct one
