Pardon my ignorance here. A couple of questions: what kind of fit on shields should you be looking for, for pain-free expressing? Lots Larger than nipple or a snugger fit?
Also, am finding my nipples and areolas swell quite a lot, even at low suction. is this a problem? Using a larger shield they get ridiculously big.
I'm not finding it very productive and hand-expressing is a disaster.
