Uneven boobs

I was exclusively breast pumping for a few days. For several reasons that I don’t want to get into, I decided it would be best for our family to switch to formula. While making that transition, I decided I would still pump but cut out every other session so I could avoid engorgement and slowly lessen my pumping sessions.

Well now at each session, I’m producing a lot more milk! It’s making me think maybe I shouldn’t stop pumping completely lol. Idk it’s such a hard decision!

But if I decide to keep pumping, I’m having an issue with my left boob barely producing any milk. Maybe like 10 mL at each 20 minute session. My right boob is a champ and will give a good 2-3 oz on its own!! (I’m 11 days PP so I feel like that’s really good lol) So it kinda gives me motivation not to stop completely, but idk for sure still lol. If my left boob could give that much at each session that would be AMAZING!!

So If I decide not to stop pumping completely, how can I get my left boob to produce more? I try massaging it more while pumping but that barely helps. I could pump a few extra minutes on the left side but I really want to avoid the extra time spent on the pump.

Also if I decide to stop pumping and just do formula, how can I get my right boob to stop producing so much? Shorter pumping sessions maybe?

Any advice?
