Hi, M.!
I have beautiful 4 year old twin boys, and I can still vividly remember the last few weeks before having them, all the questions that run screaming through your head. Really, everything will be fine. Feed them at the same time when they come home, put them down at the same time for naps, and they will get on the same schedule pretty quickly. I found that having them sleep in the same crib for the first few months works really well, they are already used to sleeping next to eachother, I think it makes it easier. For feeding, I wasn't able to breastfeed, so if you are, I have no suggestions in that area. But when I bottle fed, especially the morning bottle when they were starving, I would put them in bouncy seats on either side of me and feed them at the exact same time. It did cut into the cuddling while feeding time that I had with my first child, but I just made up for it afterwards or in other ways. :)
You will have some tough times if/when they hit growth spurts at different times, as obviously one will be eating more than the other. But, for the most part, just make sure from day one that you feed them either at the same time, or one right after another, and a big thing that I did with these two that I didn't do with my first is when I would lay them down, I would try to make sure they were still sort of awake, that they way learned from the get go how to put themselves to sleep.
I hope that helps, and if you have any other questions, feel free to email me any time! Good luck and congratulations!
