My 5YO DD will often say this. I always try to make light of it and then distract her, not in a "not addressing her feelings" kind of way (or at least that's not my intention), but in a "not wanting to make too much of it so that she stops thinking about it" kind of way. She has just said it again. I'd say it comes up around once every fortnight. She once even said "what's the point of it all if we just die?". She's only 5 FFS
