We talked about death a lot at 3. I said things like, "If you die before me, I will be very, very sad. But I don't think you will die before me. I hope you will live until you're an old, old lady, even older than Grandma, and your own kids are all grown up. Then you can die when you're ready." I'd say, "When you're dead you won't feel sad, or worried, or lonely, because you won't feel anything." If she was worried that she wouldn't be able to eat, I'd say, "Yes, but you won't want to eat. You won't even get hungry." I also have told her that being dead is just like not having been conceived/born yet--and that's not scary at all. I must have done something right, because she's got a pretty healthy, relaxed attitude about it now. smile
