In our work, we mammologists are often asked by mothers who are six months to one year postpartum how to get back their milk. The mother has to work the night shift, she has to go to work abroad, she is sick, she thinks the baby is too big, she heard from others that the milk is not nutritious when the baby is big; the baby does not eat by itself, the baby is teething and biting all the time, it is too sticky to the mother …… In short, there are all kinds of reasons to ask, and they all sound reasonable. This problem was a very simple matter for me in two years – the mother asked for it and it was back to milk. Prescriptions for oral and topical medication to restore breast milk, and instructions for the mother not to get hurt, to reduce contact with the baby, and to minimize breast milk discharge would all be done. However, many mothers are very nervous when they mention breastfeeding, thinking that it is a painful process and hoping that it will take as short a time as possible. They are worried about the long-term and short-term side effects of taking medication, and they are afraid of unbearable bloating and pain without medication. So we started to pay attention to whether there is a better and faster way or medicine to return breast milk, and how to do it with the least amount of pain. Baidu said that breastfeeding means weaning, which means weaning a child so that the breasts no longer produce milk. Is it really that simple? Why is the “weaning” period such a difficult time for both mother and baby? Does it have to be so painful to disconnect the breast from the baby? After being introduced to the field of breastfeeding, I opened the 900-page book “Breastfeeding and human lactation” edited by Jan Riordan and found the chapter on weaning. The book refers to “lactation” as “weaning”. The definition of weaning is much stricter: the process of transitioning from one type of feeding to another, it is not a mere act, but a process in which the baby starts to get food from other than the breast and gradually stops breastfeeding, weaning is not a complete cessation of breastfeeding but the addition of other types of food. If we look at the dictionary, we can see that lactation is the process of transferring the young biological individual from breast milk to other forms of nutritional state. If we compare breastfeeding to the continuation of intrauterine conception, weaning is the second birth. From a physiological point of view, lactation is a complex adjustment process that includes nutritional, microbiological, immunological, biochemical and psychological aspects. The types of lactation include gradual lactation, partial lactation (for class mothers), and abrupt lactation. Abrupt weaning is not recommended because it can cause mastitis-like symptoms and the possibility of depression, and taking medication can cause side effects such as nausea, dizziness, and gastrointestinal reactions. For the mother’s breast, sudden departure from the breast is also an injury that may affect the orderly reorganization of the breast tissue due to sudden degeneration. Contraindications to breastfeeding include: 1) congenital lactase deficiency; 2) congenital maple urosepsis; 3) phenylketonuria; 4) HIV infection; 5) human T-cell virus type I; 6) herpes simplex on the nipple areola; 7) active chicken pox at the time of delivery; 8) inability to breastfeed because the mother is undergoing radiation therapy, chemotherapy, psychosis, eclampsia, shock, or is deceased. If it is so painful to leave breastfeeding suddenly, why should we be in a hurry? There are a lot of reasons to continue breastfeeding: 1. WHO recommends exclusive breastfeeding until 6 months, after which complementary foods are gradually added, and it is recommended to continue breastfeeding until 2 years of age and above; 2. Most babies who return to the breast will continue to join formula, and the dangers of formula cannot be ignored; 3. According to the primate mammal weaning time, weight growth 4 times, reaching 1/3 of the adult weight, the first permanent teeth eruption time and other factors, human weaning time should be 2.3-7 years. Most of the reasons why mothers asked to return to breastfeeding were frivolous, because they were not given the correct information and understanding of the dangers of sudden weaning, which is what we doctors should inform. What better reason than to promote the health of the baby and the mother? So if your baby is older than 6 months and needs to be weaned, my advice is: first, recommend guided natural weaning; if you are under pressure at work, etc., you can do partial weaning, that is, gradually reduce the number of feeds and increase the interval between feeds, which usually takes a few weeks to a few months; and when a serious health threatening illness occurs, ask your doctor to assist in safe weaning.
