Jennifer,
Way to go, you are a champ!
I am also still breast-feeding my GS daughter, although we have only been at it 2 months. I am surprised that my supply keeps on going up each week, little by little, of course so does my DD demands. I nurse and i pump with the limerick. Although, i never made enough in the beginning to satisfy her, I supplememt with my own home-made formula, I make about 50% of her demands. It's enough to keep her protected. I hope that one day i will have enough for her, but it's OK if I don't.
Marica.
