DD worrying about death

[NotHavingXmasInChicagomum]

Have just dropped dd (almost 4) off at mil to go to the theatre and in the car on the way over she asked "does everyone die?" followed by "are you and daddy going to do", "I don't want you to die as I'll never see you again" and "what happens to people when they die"......

I tried to explain it all as best I could (think I did an ok job) but am rather stunned at having this conversation with her at such a young age. I could ascertain from her where she got these concerns from.

Ds started talking about death at 4y. He would go through phases of being almost obsessed with death, for a week or two at a time. We would just answer his questions straightfrwardly and simply, a bit like the sex questions, and always reassuring him that we would be with him for many many years, and that we would always love him and look after him. An answer that he seems to particularly like (when he asks about himself dying) is that there's so much for him to do - grow up, go to school, learn to ride a bike, get married, have children, and so on - that he can't possibly die for many many years.

Ds will often say to or about dh, that he hopes they both die at the same time because he loves his daddy so much.
