Ds1 (6) is going through a phase (hopefully) of aggressive play and language - games about people killing people, people killing animals (hunting scenarios) - which I am very uncomfortable with. Killing and dying are also themes in his written work at school: for example, they had to write 'instruction sentences': ds1's first sentence was "Go and kill yourself in the church."
His second was "Blow your head off." and so on...
(Should just mention that we visited a Catholic church recently and he was fascinated/horrified by the larger than life crucifix above the alter so I'm pretty sure this is where the church/dying thing comes from).
He is/has always been a very gentle boy and has never been aggressive towards another child, it all comes out through pretend play with cars or figures (so this morning Scoobie Doo killed all the farm animals). Equally he doesn't use aggressive language towards other people.
My question is, do I say anything to him or ignore it and hope it goes away? His teacher, who showed me the sentences, thought it was very funny (I was mortified).
Of course I would definitely take action if he was verbally or physically aggressive to another person but if Scooby Doo goes around slaying lambs and piglets (complete with sound effects) should I object?
