The thing about pumping is that it really helps to stay regular. I pump every morning at the same time until I see no milk coming out. Then I give a bottle of it at bedtime. If I start getting less and less, then I skip the bottle at bedtime and nurse then (takes more out) - she might be hungry for about 2 days with this and wake again for more milk, but in a short time, my supply has increased again and I can pump more. The other thing you can do is squeeze in more pumping session, but try to stay regular so your breasts know what to expect. If after a few days, you still can't get more than 1 oz, I'd suspect you're not getting a letdown when you pump. Have you checked the FAQ on pumping?
