The best nutrition for a newborn baby is breast milk. Breastfeeding provides an unparalleled opportunity for the baby's healthy growth and development. It is a biological and traditional form of nourishment. It is also an important factor in forming the emotional bond between mother and baby. Breast milk alone meets all of the baby's needs, including water, for the first six months. It is primarily a clean source of nutrition, free from the challenges of preparation and heating, and is always ready for use. It is easily digestible. With its functional components and live cells, it protects the baby from illnesses. Breastfeeding mothers also experience lower rates of breast cancer, ovarian cancer, osteoporosis, and anemia. The composition of breast milk is not fixed; it is independently regulated based on the baby's needs, regardless of the mother's diet. For example, the milk of mothers who have given birth prematurely differs from that of mothers who have had full-term births. The first milk produced in the first seven days, known as colostrum, is yellowish and thicker. It is rich in protein, antibodies that protect the baby from diseases, minerals, and vitamins. In the following days, the protein content of breast milk decreases, while the levels of lactose and fat increase. Towards the end of breastfeeding, the fat content in the milk increases (hindmilk), providing the baby with a feeling of fullness and protecting against obesity. The most important factor for the production and continuation of breast milk is the baby's sucking. The time it takes for the milk to become rich in fat during breastfeeding depends on the baby's sucking strength. Therefore, to ensure the baby receives enough of the fat-rich hindmilk, the baby should be breastfed until they naturally release the breast. The production of breast milk increases with the correct technique and frequent feedings, in addition to the baby sucking. During breastfeeding, the mother should sit comfortably, hold the baby close to her body, and ensure that the baby’s head and body are aligned on a straight line. The baby should grasp not only the nipple but also the surrounding dark area. Even if the breasts are not full after birth, it is crucial to start breastfeeding immediately to stimulate and continue milk production. Night feedings in the early months increase milk production. Fatigue and lack of sleep are factors that negatively affect milk production, so the mother needs help and support. Breastfeeding the Baby: In the first few weeks, breastfeeding is irregular, and the baby should be fed whenever they want. Ideally, the baby should be breastfed from both breasts for equal durations, but this does not always happen. If the baby nurses from only one breast at a time, the next feeding should be from the other side. Burping after breastfeeding helps reduce colic pain. The average breastfeeding duration is 15-20 minutes, and the average interval between feedings is 2-3 hours. After the fourth week, babies usually nurse every 3 hours. Night sleep intervals may extend to 4-5 hours. If the baby is sleeping, they should not be awakened for feeding. There is no need to give water to a breastfed baby.
