Over the last two weeks both my DH parents have died due to terminal illnesses. He's been away caring for them. DD 8 is aware of what has happened and due to the death of our loved family pets previously knows what death means.
DS at 3 though doesn't have a clue. I've said that we shouldn't take them back to their GP house because he's not going to understand where they are.
AIBU though to just not really tell him until he is older? He's got a pretty good memory for people though... just not sure what to do!
