Help with milk supply!

Hi there!

So I have been exclusively pumping for 5 months now. My supply has wavered a lot but lately I can’t get it to increase no matter what I do!! Things I have tried:

- super hydration (including body armor)

- IPA beer

-supplements

- cluster sessions

- lactation foods

- chamomile tea

- eating appropriate amount of calories

I feel like I have tried just about everything I can think of and have seen others have success with. What am I missing?? Does anyone have any other tips that helped them? I’m drinking SO much water and staying healthy I don’t know why my supply won’t increase 😩 it’s to the point we had to start supplementing with formula again. ANY tips would be amazing!!
