Hi! I was passing by and saw this thread, and thought of all the things I did when I woh and pumped. Let's see... I had a Purely Yours, which I loved. I got about 6-8 oz total (both sides) at my one pumping time at work. If I had a good breakfast, a good lunch, and a good night's sleep the night before, I'd get closer to 8. I took a lot of fenugreek, and had oatmeal for breakfast daily.
I tried pumping first thing in the morning, but that stressed me out because then I'd have to clean pump parts before going to work. I'd get home from work, nurse the baby on one side, then pump the other. What really worked was this-- once, after nursing him around 3 am, I found myself awake. I got up, and figured it wouldn't hurt to try pumping. I used my Avent (so I would still have clean PY parts for work) and I got like 8 oz from
one side, without really trying! It was quiet, calm, peaceful, warm (I sat near the heater)... There was absolutely no pressure, nobody waiting for me to finish, or get back to work, no TV blaring in the other room, no fussy baby.

From then on, if I felt awake enough (and ds was sleeping soundly), I'd get up after his middle of the night nursing. I pumped until he was about 14 months, then he was eating so much at daycare that bottles were coming home full. Oh, and we never had to supplement. Now, I did work 2 days a week, then 3, and finally went to 4 when he was almost a year. And I went into the office at 10 at first (but with over an hour commute, from home to daycare to work), then 9, and was off by 4, but he was without me from 8-5.
Good luck!
