Different speed & suck ?🤷🏾‍♀️

Didn’t know what to title the topic lol but I don’t know what to do about the setting when I pump . It’s an evenflo electric double breast pump with four speeds and 8 suctions .

For my right boob the 4th speed and 4th suction works to drain it to soft

Then my left boob I use the 4th speed but I have to turn the suction all the way up to 8 to get it to drain .

I know I have to latch baby to both boobs for accuracy and all that good stuff but when she latches to my left one she can barely get anything maybe a few drops

& I had a breast reduction back in 2018 where they had to take the nipple off and put it back on and so I don’t know if that’s the cause of her barely getting anything while my nerves and ducts are trying to come back together but it’s frustrating me and she’s greedy she’s an eater

I switch between formula and breastfeeding because if I don’t she’ll cry and cry and cry and she doesn’t take a pacifier 🤦🏾‍♀️so I just need some advice or opinions maybe?
