Lopsided Breastfeeding Breasts

Hey everyone, what are we doing, if anything, to try to even out our breasts while breastfeeding? Second time mom here, with a 6week old and I'm wondering if I can do this time around to make my breasts even. Baby boy has his preferred side, as they do, and I nurse him on both sides, but the left one is at least one cup size bigger than the right. The same thing happened with his older sister. Any tips on making them even while breastfeeding because in loving the sizes just want them to be sisters again lol
