Hi sarahsmama! Good for you for aiming for relactation. IT CAN BE DONE!!! You mention that you are pumping 1-2 times per day. If you can increase the number of times you pump, you will relactate faster. The more often the breast is drained, the more milk you will produce. When I had low supply, and had to supplement, I would first nurse my baby for about 10-15 minutes on each side, then give her some formula to fill her up, and then pump 10 minutes on each side. If my daughter slept more than 3 hours at night, I would wake up and pump in the middle of the night. I felt like I was constantly nursing, bottle-feeding, and pumping, but it really did help bring my milk back. In short, the more often you can pump, the better!
I think you mentioned that you are going to see a lactation consultant. You may wish to talk to her about obtaining a prescription for Reglan or Domperidone, drugs that can raise your levels of prolactin (The milk-producing hormone). If you decide to take that route, I suggest trying Domperidone first, as Reglan is associated with an elevated risk for depression. (I used Reglan, and had no side-effects.)
You might also try the herbal route- many women, including me, have used fenugreek to increase milk production. The only side-effect from fenugreek is that you smell like maple syrup, which I think is kind of nice! You can get fenugreek pills in natural food stores, or look for Mother's Milk tea (Which contains fenugreek and some other herbs) in the supermarket, or you can look for fenugreek seeds or powder in the spice aisle in the supermarket. You can put a teaspoon of the seeds/powder in a cup of boiling water and make your own tea.
