I know lots of AP sounds nutty to non-AP believers - and I'm not looking for any judgy comments - only genuine, caring helpful answers.
We room share with our 4 month olds and we wouldn't have it any other way. Night time seems to go great. We follow their cues and they're in bed by 7 - waking as needed for breastfeeding throughout the night then up for the day around 7:30/8:00 am -ish. The disconnect/new mom confusion I'm having is with daytime naps. They're tired and will fall asleep in the car, on a walk, in a wrap (but thats tough because being wrapped to one limits me with the other) or in our arms when we're rocking/singing, but just won't stay asleep when we try to transition them to their cribs or even our bed. Result is very short naps and tired babies. I want them to get all the sleep they need and right now they seem to need trusting arms to fall asleep in. I'm not worried about the drain on my time (although a consistent 2+ hour nap time at around the same time daily would be brilliant). Problem is that it's so inconsistent and I'm only one person (unless I recruit a Grandma for the day). I want to continue on this gentle sleep transitioning path but I want to know how other AP MoMs of twins do it with such young babies. My local MoMs look at me like i have three heads when I tell them we cosleep and follow cues instead of forcing a schedule, so they're not much help here, maybe you can be?

Maybe try working one at a time on getting them to fall (and stay) asleep on their own using some of the techniques in the "No Cry Nap Solution" book? Once you get one going down easily, then you can work on the other. It will probably take some time though.
I hear you on feeling isolated - I felt really down on myself for still finding all this so hard 4 months in when all the WSMoMs (are you a member? I recall you are in my area) have their babies on a strict schedule and find it so much easier after 3 months.
Unfortunately if you want to do more AP approach I don't think there is really a way to avoid the feeling you are always trying to get someone to sleep. It sucks. But it passes
