My 5yo DS is extremely close to his grandmother (my MIL). She has terminal cancer and probably doesn't have very long left. She's been in and out of hospital and we've explained she's poorly, and will always be poorly now, but should we be explicitly saying she'll die soon? He's starting to understand (I think..) a tiny bit about death/dying in general. I'm worried that if we don't it will happen and come as a surprise to him..? But I know DH is also a bit worried he'd make frank comments/questions to her if we did. Grateful for any advice.
