Good day! Ladies who have already given birth, how much did your baby gain in the first month of life? We were born at 3960, discharged from the maternity hospital at 3800, and now we're at 4098. Is it not a lot for three weeks, 298g? We're breastfeeding, I scheduled an appointment with a pediatrician on Monday. But I would like to hear your opinion too! I'm not sitting on diets, I eat what I can eat while breastfeeding. I attach as needed both during the day and night.
