We are so lucky that the boys are sleeping through the night. We have always had them on a pretty strict bedtime routine- as recommended by all twin moms - and it seems to have paid off.
We just recently stopped dream feeding the boys around 10pm. They had started acting like we were bothering them when it came time to eat, so we knew we had to give it up. The first night we didn't feed them it felt so weird not to have that tiny bit of cuddle time with them while they were half asleep and half awake. Feeding them may have been not necessary for them, but it was a part of our own nighttime routines.
Now we still go in at 10pm, but we just stare at the boys and marvel at how cute they are, how peaceful they look and can't believe they are ours. It really helps husband and I to sleep through the night.
