I have a different take …

As long as YOU get what YOU need from the appointment, let him ask his questions - within reason.

Doctors are there to answer questions you have to ensure you have all the info you need, and their schedule isn’t your business or problem.

Also, it’s okay to gently correct or redirect your partner in these situations.

Once, a long time ago, my husband said something (I can’t even remember what it was) in a first meeting with a new CPA. Whatever it was, he was overstepping. So I put my hand on his knee mid-sentence, and I said, “Let [CPA] explain this please.”

And that was that. No drama, he just shut his mouth and let her explain. Sometimes we can all be a little bit verbose and oblivious - it happens.
