how much milk are breastfeeding mommas making at 8 months

Alissa
My supply has really dwindled the last 2 months and I'm wondering if anyone else is dealing with the same issue... I am 6 weeks pregnant but it was decreasing before I was pregnant. Today was my lowest day. I pumped and stored about 10 oz less than what my son consumes at daycare.. I have a decent stash, 400oz+ but I'm not putting in what's coming out. I really wanted to make it a year!
