Disaster monday :laugh: (sorry) It sounds like an excellent idea, but I know some 8 year olds that would get nightmares from that sort of thing. Could you imagine trying to do something like that in a school setting? lol!
FWIW, I would consider bringing back diaster monday, maybe play around with the day of the week you do it on, or only do it 1-2x/month to avoid the feeling of constant disaster. You want your kids to feel prepared for a disaster, but you don't want them to feel like every time you leave the house disaster will most likely strike.
My idea of a disaster monday would be role playing the disaster. One kid role plays like they are in the situation, and one parent and the other kid talk them through the situation (as much or as little talk is necessary) . In some cases, kid 2 might need to play the part of the robber or wild animal or bystander, for instance. Having one kid be the "victim" and one be the "bystander" would teach both what to do if you are in the situation, and what to do if you see someone in the situation at once.
I would hope that role playing, as opposed to just talking about the situation or watching a video, would help them feel more comfortable about not only the idea of the "disaster", but about getting through the "disaster" safely. Because the whole point of this exercise would be to prepare them in case such a thing ever happened.
