DS is 4 and a half, started school in september and since then I have noticed an increase in greediness and ungratefulness in him. I've tried explaining that a lot of children don't have any toys at all (when he's moaning about not having enough cars) or some have to eat rice every day (when he refuses his tea) but I don't think he really believes me.
Does anyone know of any resources to help him understand just how lucky he is, and learn some empathy and social conscience? Maybe some short films on Youtube, or books I can show him? Preferably something he can relate to rather than Oxfam-type adverts which I think are more designed to pull at adults' heartstrings.
