LET ME TELL YOU ABOUT THESE!! 😮‍💨🍼These collection cups have been a total game changer for me! They are actually portable pumps that Legendairy Milk makes called the Imani pump. They have motors that can click on top OR you can use them as collection cups with a wall pump! You can connect these to almost any pump motor! The flange is silicone, so they are really great if you have elastic laddies!! Such a game changer and I wish I had them earlier on in my pumping journey. pumpingmom breastfeeding increasemilksupply lactation ebf
