Does lack of sleep cause milk flow reduction?

Emilee

I have been pumping after my morning feed to build a stash for when I go back to work in two weeks. I normally get 2.5 oz or more. This morning I got 1.5. Baby girl has been cranky the last couple days and nursing more frequently, but for less time. Therefore, less sleep for us. Is it normal for production to decrease from exhaustion?
