how I keep my supply going

I’ve been trying to produce more milk and I’ve been unsuccessful, I was making enough and then in a day boom I was under supplying, I’ve tried oatmeal and eating protein, and I’m still an under supplier, I’ve tried power pumping and making maybe 1ml per session, and I really want to just make enough to feed my baby because I want to. Did you have any pumping schedules?

i upped my milk production by drinking a gallon of+ of water a day! i was a slight over producer
