Well, I don't think that sleeping in the same bed, like a family bed, is necessarily wrong. Many cultures all over the world do that, and sometimes for many years. Sometimes it's out of necessity, like a large family in a small house or apartment, and sometimes it's something that some families prefer to do. Instead of thinking of it as wrong, maybe it would be better to think of it as not practical. Unless you have a HUGE bed, it's going to be uncomfortable with two adults worrying about rolling onto a baby or a baby getting tangled in sheets and blankets, and two babies who will be stirring in their sleep and very possibly keeping you and your husband awake.
We didn't do the family bed in our home partly because we were worried about sleeping ON our babies (my husband is big-boned and heavy), and partly because our first baby (Josie) was Touchy and easily disturbed and I wanted to get her on a routine as soon as possible. That worked so well that with Natalie (my second) we just started her off in her room too.
With Josie I found that sleeping in my room with a monitor didn't work because my DH (dear husband) snored so loudly that I needed earplugs, and then I couldn't hear the monitor, so I ended up sleeping on the floor in Josie's room for a couple months. My DH also had shoulder surgery during that time, so it worked out well for us both. I could get to the baby easily, and he needed a bed without me turning over and getting in and out for a week or two while he healed.
Maybe if your DH is insistent that the babies have company in the same room at night, you could start them off in their own room and take a couple nights each sleeping in their rooms with them while the other parent gets less-disturbed sleep in the regular bed. If you are planning to use bottles for at least some feeds, you can express milk into bottles so that your DH can take some of the night feeds and give you better rest.
One other thing to consider is that right now yu don't know what your babies will be like. They may be wanting to have you around all the time, or they may actually PREFER to sleep alone - Josie probably would not have slept well in our bed unless she was actually sleeping ON one of our bellies, and Natalie ddfinitely preferred her own space. I found that no matter how many plans I made about how I'd do this and that and the other, the babies often had other ideas, and changing my plans to work with the way THEY were was MUCH MUCH easier than trying to do something that clearly was not going to work with my baby. In other words, maybe you want to give one strategy a try for a while, but be open to changing it if it doesn't work for your family - and also be open to changing it if it works for a while but then something different is needed later on. Make sense?
Good luck, and keep us posted.
