Lis-Your milk won't run out, but it is a very time consuming process. If you're adamant to give her breastmilk the I say try and persevere with booby feeding. Danni, on the other hand, would disagree, as she has a huge supply and only takes a few minutes to express enough for one feed. Everyone is different though, and I'm weak and ended up bottle feeding. You can go on maxalon or motilium for supply issues also.
