Body armor hydration drink and coconut water helped my supply increase. We had to supplement with formula almost once a day for the first 6 weeks then I was able to exclusively bf. As far as pumping I found the electric pump worked best on a higher setting and the milk flow was better after a hot shower….. it also sounds like you are stressed and exhausted. We had very little help and doing it all while recovering is very hard on your body. I had to learn to find relaxation where I could and let my partner do most the cleaning even when I had the urge to get to it quicker. Sending love and energy Mama!
Also when baby seems frustrated during a feeding try switching boobs or changing positions.
I should also add that I was on antibiotics for 7 days but still getting pain and blockages. Tried all the tips from massages, pumping, cold and hot compresses as well
