Increase breast milk supply

So I don’t breastfeed, I strictly pump. My daughter won’t latch and I’m not going to stress myself to try and get her too. It’s my second and my first never did it. I believe the stress of trying to get her to do is what made me dry up last time.

But I want to boost my supply. My last experience was so bad I had crossed evening trying to breastfeed or pump off the list. Well after trying to dry up my milk for weeks and it still not going away, I have taken it as a sign to try. How can I boost my supply so that I’m getting a decent amount. My daughter is on formula and doing good with it but it’s not like receiving both will hurt her. All the tips I look up on boosting supply involve things like get a good latch, don’t skip on feedings, don’t give a bottle. But I need tips for strictly pumping. Anything you can suggest is greatly appreciated. 😊
