Hi mummies .. i am an exclusive pumping mum and i observed that one of my nipples had a white little bump which looks like either a blocked milk duct or a pimple with pus. I tried to burst it but couldnt. It has been aching on and off. My question is if its a pimple and assuming the white substance is pus, is it still safe to feed my LO the milk excracted from this nipple? Every drop counts so i really hope it's fine. Really needs help now! Tks!
