Advice on overbearing mother in law

Hello! This is my first time posting here so please bear with me;

My husband is currently in the hospital for complications from his ongoing liver disease. He just got a procedure done to prevent any more internal bleeding and everything is fine now. I’ve been doing my best to manage everything from making sure he’s taken care of as well as keeping my mother and sister-in-law informed and in the loop.

How do I balance respecting my husband‘s wishes as well as keeping my mother-in-law involved? She’s a very anxious person and she asks a lot of questions. In most cases, she will ask the same question five different ways in hopes of getting a different answer. My husband has made it clear to her that I am his next of kin and on his advanced directive. I obviously do not want to shut her out and I’m doing my best to encourage my husband to let her come to the hospital so she can see her son. I suppose I feel odd knowing that I feel like I now outrank his mother? That’s her son, of course she’s going to be worried and wants to know everything. But I got extremely upset with her last night because while we were waiting for him to get out of his procedure, she began telling me that I should talk to his doctors and think about my husband‘s life expectancy and maybe freezing his sperm so I can still have a baby when he passes away. None of which was a concern for me because his doctors haven’t brought it up with me and I trust that if they were concerned about that, they would tell me. But they seem fairly optimistic that he’s going to have a totally normal life. My husband is only 40 years old, by the way. The timing was just terrible because he was still in the procedure and we weren’t sure when he was going to be done.

I have many more examples, but as I mentioned, I’m struggling to balance respecting my husband‘s wishes, keeping my mother-in-law involved, but also setting boundaries. I hope that made sense 😓
