Some people pack only basics for themselves..however I pack going home outfits, my own diapers, wipes, clothes for baby, clothes for me, boppy pillow for breastfeeding..i go overboard, always nice to use my own things..but hospitals usually provide everything except a going home outfit and carseat of course...you can google "hospital bag" and it will pop up lists of things you can consider bringing. With twins I assume you'll be having a c-section, my advice to you is bring a high fiber snack, lol! Fiber one bars, something, because constipation is REAL after a c-section and they usually ask that you go to the bathroom before going home. Also loose fitting clothes of course so it doesn't rub on the incision too much. That's just a couple things I always have as a c-section mama. I'm due with my 3rd baby, 3rd c-section.
