My DS says this when he has a consequence for having done something wrong (being rude and having something confiscated, usually).
He threatens to leave and even goes so far as to get his lamb lamb and head for the door!
I know it sounds silly, but if he can want to leave and think of it when he has just turned 6, I worry about what he will do in his early teens and beyond.
I'm a fair and kind parent but he also often tells me that he wants a new mummy. I pretend not to be bothered. But I am.
Even though he's only sent to his room (6 mins) or something is confiscated if he's really rude or naughty, he gets so angry and frustrated that he's even said a few times that he wants to die / cut himself up into little pieces. That I find highly concerning. I called CAMHS recently. They didn't seem to be particularly worried.
Is this really normal for a 6 year old in year 1?
