My 5year old occasionally has a moment where he'll say not-so-nice things. It starts with standard poo/wee stuff which he finds amusing but then turns slightly aggressive!
"I will poo in my pants and throw it out of the window and then I'll kick you in the tummy and smash Spiderman's face". For example!
Sometimes he just says it laughing, sometimes it does sound a bit aggressive and goes on and on. Usually at the end of the day when he's tired and cranky. It seems like the way he lets off steam and frustration at the end of the day (similarly to how as a toddler he would have had a full meltdown).
Is this normal-ish and how should I respond to it?
