Girls, good day to you all! I have a question: my daughter is on breastfeeding, but literally a couple of days ago I noticed that milk in my right breast has been disappearing and doesn't come as often, the breast isn't getting bigger like usual ?. The left one is normal, it's in its own rhythm. I feed her alternating between breasts, of course, the left one takes more than the right. But what should I do? During a visual examination, I see asymmetry in the breasts... maybe someone has encountered this, could you give me some advice please ???
