So my son's best friend came over (they're both the same age) with his parents. They absolutely love playing and it was fun having them over. However, about 30 minutes in, the boys were running around the living room while me and the parents chatted and then my son suddenly shouted, 'Im gonna kill you' but he was laughing his head off and so was his bestie. But I was shocked that he said this and I immediately looked at his parents who went wide eyed and I immediately apologised on my son's behalf. He never said it again but it was so freaking embarrassing to hear those words come out of my son's mouth. The rest of the day progressed smoothly with some normal and typical issues like not wanting to share toys, some pushing and not listening to directions.
My son obviously is too young to understand the concept of kill/death and that killing is associated with being harmful towards others but I most certainly do not want him to say that to anyone. I can tolerate it when he says things 'The spider will kill the monster!' when he is playing pretend with his toys but Im really not comfortable when he says that to actual people. Is there anyone here whose toddler has said these things before?
