Girls, who's on GVB? Please give me some tips from experience ? We've been nursing, a couple of days since it came in milk. But I already want to quit ? There's a lot of milk, straight pouring out. The baby eats one breast, and the other is full for the next feeding, just dries up and hurts. And milk flows like a river from it. Maybe there are some tips, secrets... how to quickly fix all this? ?
