Review on Maymom Wide-Mouth Milk Storage Collection Bottle With SureSeal Sealing Disk; Compatible With Spectra/Motif Luna/Ameda MYA/Bellababy Pumps. Can Replace Spectra S1 S2 Bottles, 6 Pc (4.7Oz/140ML, 6Pc) by Josue Zepeda

Ok so I've been using lansinoh bottles since birth and my baby only drinks from that nipple. I've tried transitioning to others but he's just not ready yet and I'm in no rush. The only issue is that with lamsinoh, the biggest bottle is 8oz. I started to overfill it to 9oz because it seemed like he would want more, but it leaks. I just used it tho because lansinoh for some dumb reason, doesn't make bigger sizes or even transition nipples. I am so so glad that I found this! I overfill it up to 10 and no leaks. The lansinoh nipples fit perfectly into these rings. (The lansinoh rings didn't fit properly) all I care about is that nipple and I'm so so happy. Only issue I had was that it required a signature for delivery and USPS came and didn't ring the bell or anything so it was a hassle to get it.
