Need some sleeping advice with Irish twins.

This is kinda long but it explains how I'm feeling.

I am torn on what to do once my second daughter arrives. I had my first daughter on 09/30/2019 and this baby is due on 08/21/2020. My husband helped out so much when our daughter arrives and is always up thought out the night and morning until I get up with her now. But I don't know what to do when this one arrives. I tell him that if wants to sleep out in the living room to get full night's of sleep I'll be okay with it. But the he says it's not fair to me. I then go back and tell him that someone needs to be will rested for our first daughter. And I'm kinda worried about putting this baby in the nursery with our first daughter (we only have a two bedroom at the moment). I don't want our first daughter to constantly woken up by this baby. I do have a bassinet that I used with out first daughter. But then again I go back to the sleeping issue with my husband.

So I guess what I'm wondering is how you handled a good sleeping routine with your husband and Irish twins.
