Hello everyone. It's been 34 days since childbirth, mixed feeding because there wasn't enough milk for the baby. I can't understand why, as the weight is now just 1kg from the weight I weighed at birth. It was -2,-3, then two kg returned. I started eating more, of course, as the appetite is strong with breastfeeding, but I eat properly, not overindulging, as I had problems with sugar in the past. My face is constantly swollen. I wanted to ask someone who experienced this, when did the weight go down? What was the reason for the weight increase? Could it be edema?
