    To be clear, the return of menstruation after childbirth will not affect the nutritional value of milk at all. At most, a small number of mothers will experience short-term fluctuations in milk volume during the menstrual period, which will not delay normal feeding of the baby at all.

    A while ago, I accompanied my sister to a community for child care, and I met a mother squatting in the corridor crying, saying that her aunt came just 4 months after giving birth, and her mother-in-law stopped her from feeding her, saying that the milk was "dirty and unnutritious", so she insisted on giving the baby milk powder.

    In fact, it is really a misunderstanding. To put it bluntly, the resumption of menstruation means that the ovaries have resumed their ovulation function. The estrogen will temporarily increase a little, which slightly suppresses the secretion of prolactin, so the milk volume may be a little less than usual. When the hormones fall back after the menstruation, they will immediately return to the original level, which will not change the nutritional content of the milk at all. The old sayings of "toxic" and "no nutrition" have no scientific basis.

    Of course, there are also many mothers who say that they haven’t returned after their aunt’s milk supply. I have specifically asked maternal and child nutritionists before, and they said that most of these situations happen to coincide with the baby’s surge period, or they stay up late to take care of the baby, drink less water, and fail to eat during that time.

    Don’t panic if you really feel that your period baby is not eating enough. Let your baby latch on and suck more. Express yourself for two or three minutes after each feeding to stimulate lactation. Drink more warm milk, warm peanut soup, etc. Don’t rush to add milk powder just listening to the old man’s nonsense, as this can easily lead to a decrease in milk supply. I have seven or eight mothers who came to my aunt early. They all nursed their babies until they were more than one year old. All the indicators in their physical examinations were excellent, and they were not affected at all.
