So baby is 6 months, and I'm suddenly pumping NOTHING. I'm drinking teas, eating oatmeal, taking fenugreek, I'm not getting a drop. So I got Earths Best sensitive organic formula, since we use Earths Best food. He HATED it. Spit it out immediately. Fine. I gave him an individual packet of similac and he drank it down like it was a milkshake. Awesome. I tried it again the next day and he spit it out like it was poison again. I tried a third time, and he spit it out again. Ugh. So I bought some organic Happy Baby formula because it has lactose instead of corn syrup, and SURPISE. He wouldn't even get it the whole way in his mouth he made such a horrrible face.
