Sooo this is my 3rd baby but 12 years apart from my last. Breastfeeding this time has been completely different and it’s the longest I’ve done it. Babes is almost 5 months & only wants boobie milk. I am an ICU nurse and back to work so I have the M9 and I’m loving it. But I’m wondering if buying the Momcozy cooler bottle to put my pumped milk in is worth buying? It’s just a little expensive. Any thoughts from those who have purchased it would be awesome!
