Girls, good day, listen, I'm leaking milk from my chest in the literal sense, my shirt is wet all over for about 5-7 minutes. Pads for breasts also for several minutes, the daughter doesn't suck properly, so every 4-5 hours, not hungry at all, everything is fine, I'm pumping even more milk comes out... what is this exactly? ??
