Congratulations! Do be prepared for lack of sleep, but don't worry about it. Our first slept approximately 4 hours a day until he was nearly 2, as do all the males in my family, but the girls would have to be woken for feeds - YMMV.

One of the most useful things we did was to make the last feed of the evening from formula, which meant that I could actually do something useful that didn't involve the smelly end of the babies. Invaluable, both for me to get some time with the babies, and for SWMBO, to get some sleep.
