I have 6 month twins and have exclusively pumped since day 1. while I didn’t start out with the mobile flow hand free set, it is by far my most favorite as I seem to get the best output, comfortability, and even pumping 2-3 hrs the battery last pretty much all day. my biggest complaint is the flanges. I have replaced EIGHT flanges because the prongs on the bottom keep breaking. I have tried everything in making sure the alignment is just right, not pulling at an angle, hand washing only instead of thru the dishwasher/ bottle washer, keeping them out of the fridge in between Pump sessions and NOTHING has worked. last night, it happened again and I am beyond frustrated. This keeps happening! I’ve already tanked so much money in buying new pumps, extra parts on top of trying everything I know to increase supply for twins, that I’m just wanting to call in quits on breastfeeding. BUT my twins have been so successful, and I have no other option. what am I supposed to do???
