Okay I've looked it up but still am not completely sure. For those that pump- are your nipples red? All the time literally. I'm wondering if my flanges are still just slightly too big for me... does a little bit of the areola surrounding your nipple get sucked into the flange? Like a centimeters worth circumference.  Just wondering if I'm doing something wrong or this is the typical thing when you pump. I just feel like my nipples aren't suppose to hurt and be so sensitive allllll the time. If this is normal what do you do for your nipples- just the normal lansinoh and other nipple creams? Thanks mommas
