How to help husband, his Grandma is on hospice and hes falling apart.

He went to see her for the first time in months, he just called me in tears. Shes on hospice and doesn't have long. I lost my mom and dad (2007 and 2019) both on hospice but I managed to handle it well as I was a CNA for a long time and have seen a lot of deaths and worked with many hospice patients. Hes never really lost any family except his Grandpa when he was 8. When my dad was put on hospice my husband tried his best to be there but didn't do the greatest job, they didn't get along sooo. I want to be there for him as much as possible, anyone have any tips? Should I try to have him talk about it, let him bring it up and talk when he's ready. Let him just do his own thing and go through the process. We have a full stressful house, Im pregnant and due early Sept and he sooo wanted his Grandma to meet this baby but it doesn't look like that will happen. Any advice?
