low supply

Brett • Wife, Momma to Ben, Fur Momma to Tank, Squatch, and Mojo.
I was exclusively pumping but my supply was t able to keep up so we started supplementing. I am completely hydrated, have. Even eating oats, drinking the tea, taking the tablets and pumping every 2-3 hours and my supply SUCKS! sometimes I get 6-7oz combined other times I'm lucky if I can get 3oz combined! Idk what to do or what I'm doing wrong 😭
