Very much this. My daughter was bottle fed, and almost like clockwork she would get hungry every 3 hours, at 12, 3, 6 and 9. My wife would feed and go to bed at midnight, and then I would stay up until 3 and feed there, then straight to bed. Then at 6 my wife would wake up and feed, and then finally at 9 in the morning I would wake up. Getting those 6 hours uninterrupted was invaluable.
