Hey A.,
I was a full time working mother that pumped for 11.5 months, but I could not have done it without Fenugreek (3 pills, 3X per day) and Reglan. You have to get this from your doctor. I used Reglan for months. Usually I would use it and build my supply back up, then as soon as my period hit, my supply would tank again. So right back on the Reglan I would go.
I also had to supplement with formula. I rarely was able to pump enough to give him all breastmilk. Also, my son would not nurse until after I started back at work unless it was in the middle of the night. At that point, I don't think he cared as long as milk came out of it! :-) Pump as much as you can at work, but use the weekends to really pump as much as possible...like every 2 hours during the day. It may mean you have to stay around the house verses go a lot of places...it will take sacrific!
Also, have you tried breast message before and while you are pumping. I would double pump to begin with, and then pump one breast at a time while messaging to push the rest of the milk down and out. Or if you are really talented you can double pump, hold them with your forearms and message both breast at the same time.
The thing about it is, do the best you can do and leave it at that! Feel good about yourself that you are trying! And, if it gets too hard or you aren't getting enough milk to keep pumping, pat yourself on the back for what you did do!! Any amount of breastmilk that you give her is good. It's definately not a all or nothing kind of thing!
But please call your OB and tell him you have tried all of the natural ways to boost your milk supply and ask for a prescription. The Fenugreek helped, but no where near as much as the Reglan. That stuff is amazing.
I know how hard it is to work and give breatmilk...I fought through all of the guilt as well. The best of luck to you!
