Breast milk regulation?

Jocelyn

I breastfeed my 9 week old and pump the occasional bottle for my husband to feed. I pumped today following a feeding and only got about 2 oz, whereas before I’d get anywhere from 4-5 oz. I feed on one side per feeding, and feed every 2.5 hours typically. My boobs do feel softer and less full. Could this just be my supply regulating? I do feel a bit dehydrated today too as I drank less water than I normally do, could that be a cause as well?? Ughhh I’m stressing now that my baby won’t get enough 😭😭😭
