Pumping. It ended up that I had to do it if I wanted my kid to have my milk (would he have starved 100 years ago? No idea!) but it had the excellent side benefit of being able to separate output from input, and my husband was able to pop the bottle into the little gaping mouth, and I got to where I could get all the little guy could drink and some extra in three long blocks per day.
Even if direct nursing is going well, I highly recommend doing some pumping along the way from early on so that if/when she needs to be away from the baby for a few hours, it's not as big a deal.
