My great-grandmother is 96 and in hospital. She's suddenly become very poorly these past two days and has had the priest come to see her and they don't think she will make it through the night. She lives with my parents and we see her 4 times a week, and my son adores her.
Now, although the past few years we've lost one or two family members, it's never been anyone DS has really knew, more distant family, and he was only a baby, so we've never had to explain how people can die and what happens afterwards and the finality of it all..
Explaining this and telling him he will never see his beloved Mother again is going to be worse than accepting it myself. How do I do it? It's going to break his world into two 
Even though she's 96 it's just totally unexpected
it was only this last week she got ill, and it started as a cold, and now 

please, any advice appreciated x
