I agree that it really might be tricky to try this so early on. I weaned to to feeds a day, but not until dd was over a year and my supply and the breastfeeding relationship were very well established. We kept up those two feeds for almost 10 months. However, I know some moms can't keep up a supply on only two feeds a day, even after a year. It really all depends on your body, but I'd guess it's going to be tough to keep up your supply this early on.
