Why or why not?
How old are they or were they when you talked about it?
I'm kinda having an issue. I never spoke to my son about it. He is 9. I don't think he needs those kinds of worries about the world around him yet. I didn't plan on shielding him from everything forever but I wasn't ready to talk about it with him (or my 4 and 2 yos for that matter!) Yesterday, he came home from school and told me they watched a video about 9/11 and in his wide eyed terror stricken face he asked all sorts of questions about it happening again, him NEVER wanting to ride a plane again and many other topics that were tough for me to cover with him.
I really wish the school would have warned us they were showing something so I could at least have been prepared.
