Hi all. I have a Medela Swing that worked fine at first but now it's sucking my nipple in and not releasing it fully, once it goes into the extended suck phase. After a few sucks, my nipple is completely stuck in the pump and it stops pumping (I can let go of the pump and it hangs there on its own). I have to break the suction and it'll start pumping again but the same thing happens again. I have to pop it off after every second suck and, needless to say, I'm not getting very much milk before I want to chuck it across the room.
I have tried completely disassembling and reassembling (like when sterilising), changing the white membrane thing, using the other breastshield that came with it and using mains power instead of batteries but it hasn't fixed the problem. I used it for 3 days with no problem, this started happening slowly since Tuesday and now it's constant. I'm pumping after BFing to wean my baby off formula and this is extremely frustrating.
Anyone had the same or a similar problem?
