Hello again firehorse
Children when they are at a young age seem to be very open to all these topics, which is wonderfull to see.
I guess, looking at my own experience i would have felt that if my parents thought me more about death and how there is nothing to be feared from it i would not have felt so bad when i heard about the other not so good stuff.
It would be wise to be carefull how you use words when talking to your child about sensitive matters. Get her open to the idea of possibilities, and probabilities. And when talking to her about something that you realise might upset her sit down and think of a way to word it that will give her the general idea without instilling any fear.
Can i ask, what was it that you intended on telling her that has you concerned about how she might take it?
