A.S.
Fenugreek worked great for me. I breastfed my son for 25 months and used it throughout the whole time on and off when ever my supply needed a "boost"! I used to take 3-4 with breakfast, 3 with lunch, and 3-4 with dinner.
Have you tried pumping in the bathtub? Sounds wierd, but the warm water and you being more relaxed will help your flow.
Also, place a warm wash cloth on the top of your breast while pumping.
Eat Oatmeal for breakfast.
You have to make sure you are getting MORE than enough water. Stop coffee, caffine, make sure to stop smoking if you smoke, eat 5-7 small meals throughout the day instead of 2-3 big ones.
Make sure you're massaging the breast while pumping.
Have you checked out Kellymom.com or your local LLL?
Also - do you have a high quality pump? A good quality hospital grade pump is best. Evenflo brands are horrible! Gerber isn't too good either. Make sure you have a dual electric! Medela would be my first choice.
