This is huge for me! Since he was born, he's had issues latching onto this side. It's inverted and he has refused it and fought for over an hour one day. So I started pumping and giving him formula. Then my supply started to decrease. I finally after 2 weeks got it back up. And now at 2 months, I am attempting to go back to exclusively breastfeeding and pumping. No formula at all. Yesterday I gave him just breastmilk and breastfed him. And today he latched onto this one without a fight! For anyone having issues, please don't give up like I did. This is beyond worth it
