Firstly, I hope this does not seem too trite, particularly to those dealing with bereavements.
But, my DD (2.2) loves wildlife, and has become particularly devoted to ladybirds. We have loads in our garden, and some have died. And she knows there is something wrong with them. She points at them, and says 'ah', looking worried.
I don't want to say they are asleep, because I think this is muddling and potentially disturbing. But I feel she is young to take on the finality of death.
There is a part of me that feels that ladybirds are a relatively safe starting point, and that there will come a time when we have to face the very upsetting deaths of family members, but even so, I cannot think how to start this without ending up in deep water.
She is starting to understand separation, 'DD very sad leaving Honey (our cat) in cattery'. But death seems such a big thing to lay on her now, particularly when it is not forced by bereavement.
At what age did you start this conversation with your DC's and how did you begin, particularly if not prompted by bereavement?
