Wow, what great news! Glad to hear they're so healthy. Mine were preemies and about the same size. The NICU forum here helped.
Has your friend joined the local multiples group? There are twins groups that usually have some triplets and quads in them, and there are high order multiples groups, like MOST (Moms of Supertwins) for triplets+. http://www.mostonline.org/
Those kinds of groups are going to be the most help for them. I know my local club arranges meals to be delivered to a new MOM's house, matches you up with other people who have had preemies, and has a big loaner library of gear. She doesn't necessarily have to buy lots of gear, through a club she could use it for free as long as she needs! They also usually have yearly sales where you can get good deals on clothes etc. Anyway, I'd highly recommend looking into that, and if she doesn't have time, maybe you could do the research for her and present her with the options available in the area.
I also want to 2nd the idea of a hospital grade pump. Maybe (hopefully) her insurance will pay for it, but if not you can rent them privately. Also, if she doesn't respond well to the pump, she can swap it for another. I tried several and finally realized that the Medela Symphony was the best pump out there (for me). I had to rent it privately because my insurance co didn't offer that one, but it was worth every penny. It took us a couple of months to go from pumping only (supplementing with formula) to exclusive BFing, so if she knows that even a rough start doesn't mean the end of BFing, that will help. It's nice to have hope that things will get better. The LLL multiples book will help her, too.
I can say that one of the worst things about having preemies in the NICU was having to find time to come home and eat and sleep and pump. Anything you or friends could do to help her get easy meals for a few weeks so she can maximize her rest until the babies come home would be appreciated, I'm sure. Also, after a c-section they told me I couldn't drive for 2 weeks. DH went back to work so he could take his FMLA time when the babies were home, so I was often stranded at home, unable to visit the babies. Maybe talk to her about the logistics when she's ready, to see if she might need someone to drive her. Make sure she brings snacks and her pumping parts to the hospital so she can pump while she's visiting. When they first come home, if they have no health issues, they will likely be sleepy preemies for several weeks, so that is a good time for her to restock the meals in the freezer. I wish I'd taken more advantage of that time, but I was so overwhelmed. Having a plan will help!
ps Almost forgot--laundry!! That stuff piled up like no one's business. Is she cloth diapering? She may need 2 washing machines. With twin babies + a toddler I know we were averaging 2 loads per day. (We had a diaper service so we didn't have to wash our own cloth, thank goodness we were saved some loads each week!) Friends could help by either coming over to do laundry or stopping by to pick up laundry and then return it folded, and put it away. Folding and putting it away is always the hard part.
