My MIL is dying from lung cancer and only has 1-2 weeks left. She has suddenly deteriorated after the cancer has spread, just 2 weeks ago she was dancing at a party. Our DS is her only grandchild and she sees him twice a week, they have a wonderful relationship and she dotes on him.How on earth do I prepare him for this ? So far I have told him she is very poorly in hospital, we are visiting later which could well be the last time he sees her which breaks my heart.
