My girls are almost 2 1/2 (how did THAT happen?). They were in NICU the first week & did get bottles then, but thankfully never had any issues w/ nipple confusion as a result. After that, for the first couple months, if I was going out for the day I would pump & bring a bottle of EBM in case they both wanted to eat at the same time (I'd nurse one & my mom, dh, or a friend, whoever was w/ me) but then they started refusing bottles so I stopped bothering (and figured out how to nurse them both in public LOL). What I found was that the hassles of washing bottles/pump parts, etc. were WAY worse than the "benefit" of letting someone else feed them. If your family/friends want to help, they can do everything else. For months my mom would do my laundry, dishes, fix food, clean, etc. whenever the girls were nursing (I miss it now that they're happy to play w/ "Mama" all day when she's here & I get stuck doing the household chores I don't have time for the rest of the time while she plays w/ kids LOL).
We never even had cribs, my dad built us a twin mattress sized cosleeper that's attached to our bed & they coslept until they were about 19 mo old. At that point we night weaned & they were sleeping through & seemed to not want to be touching anyone anyway so we moved them to twin mattresses on the floor in their own room & they did fine, so that's where they sleep now. If one of them wakes up she usually comes & gets in bed w/ us (we still have the cosleeper attached). Last night Ashlyn must have woken up sometime between 2am (when dh came to bed) & 3:30 (when I woke up to pee), but neither dh or I heard her. When I woke up to pee she was sleeping in the cosleeper (which means she climbed OVER me to get there LOL) & slept there the rest of the night.
Anyway . . . I have the advantage of my family being very supportive of breastfeeding (I have pictures hanging on the wall in my bedroom of my great grandmother nursing my grandmother, my grandmother nursing my dad, my mom nursing me & me nursing my girls), w/ the cosleeping I just made sure to always present it very matter of factly "here's what we're doing" if they asked I also presented them w/ quotes from Dr. Sears, etc supporting cosleeping. But in general I've found w/ most people if I'm confident (or portray confidence) about my parenting decisions they're less likely to try to talk me out of it (then again, people who know me know that I'm stubborn as a mule & trying to talk me out of it is just going to make me dig my heels in LOL).
I know it can be hard to go out w/ twin infants, but maybe look into the LLL meetings in your area or something along those lines (or check the "tribe" forums here & see if they have get togethers in your area) to find others in your area who have similar parenting styles, even if they don't have multiples, the parenting styles can be the same & the benefit of moms of singletons is they're more likely to have an extra hand to help you juggle your two
