How did you know? Just from pumpin output? I have had a cold for several days, nothing serious, just feeling crummy. I don't usually pump so I can't go by that, but C has been very quick with nursing, which assumed was just normal getting older and more efficient, but the last couple of sessions I felt like maybe she wanted more but it wasn't there? Or, I'm being paranoid. Her sleep has also been crap, but of course it could be any number of things causing that- including hunger.

Going to really increase the water and have more oatmeal just in case, but how do you know when your supply dips?
