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 :(
