Pumping question

Chelsey • I'm married and have a beautiful little girl and a handsome little boy. Everything I have I owe to Jesus

I was breastfeeding my son, but he wasn’t latching right and I was in terrible pain during every feeding. I tried the nipple shield and I started bleeding using those and my dh said I tried, but I need to stop since it was causing me so much misery. I stop cold turkey and I got engorged so I used cabbage leaves for 2 days. I was still leaking milk so I started pumping. I’m only getting about 1 ounce at each pumping session. What are some ways besides oatmeal and Gatorade to boost my milk supply some? I’m fixing to go back to work, but I would like to get more than one ounce each session.
