I'm using the mendela pump in style and find that compared to manually using my hands to express milk, using the pump expresses much less.
I am wondering if it is because the breastshields(size M) are too large for my nipple.
My nipple hurt after pumping,they feel like they have been sucked out. During pumping, some aerola is sucked into the funnel. I was wondering if this is an indication that the funnel is too large?
I have measured my nipple size before pumping and it is 17mm. (the nipple does swell during pumping though)
Shld I get size S shields(21mm) or is the standard M a better fit?
