Hi. I am so sorry for your situation but if the children think he is getting better they could feel incredibly betrayed when he passes and may lose their trust in you as their remaining parent. You don't want to upset them but sadly the upset is going to happen anyway and based on what other people have told me who weren't told a parent was dying - they were still traumatised more from being kept in the dark and things not being discussed with them more than the loss itself. Children need to feel they have some control to feel safe and that control can come from being prepared, being allowed to show negative emotions, making memories in the time their dad has left. My mum was blindsided by her mother's death as a child because no one talked about it/told her it was a possibility. She still struggles with it 60 years later
