Power pumping

Hey ladies! I had my LO March 5th via csection, and I’ve been struggling with milk supply ever since. I’ve been working with a lactation consultant who advised nursing on each side, topping up with pumped breast milk and pumping. I’m also on domperidone to increase supply. I’m getting 1.5 ounces per pump. LO wasn’t gaining much weight is why all these measures.

Anyway! Has anyone tried power pumping to increase supply? Has this worked for you. pumping after each feed isn’t ideal. Help! 😩
