After 280 days of gestation, the child is finally born, and the main job of the pregnant mother is to feed the baby. Half an hour after the delivery of the placenta, the anterior pituitary gland secretes a large amount of prolactin, which acts on the membranes of the mammary gland’s alveoli to promote the synthesis of various components of milk, such as lactose and triglycerides. As a result, milk is stored in the alveoli of the mammary gland. After the baby sucks on the nipple, the sensory nerve endings in the nipple are stimulated, and the pituitary gland produces prolactin and oxytocin through a series of complex reactions. Prolactin acts on the myoepithelial cells of the milk ducts and on the muscle cells around the breast, thus transporting the milk stored in the alveoli to the outlet of the milk ducts and into the mouth of the baby. The prolactin reflex is more likely to be facilitated or impeded by the mother’s thoughts and emotions. A mother’s good mood and confidence in her ability to breastfeed can promote the reflex; images and sounds of the baby and the mother’s touching and touching of the baby elicit feelings of affection from the mother that are conducive to the establishment of this reflex. On the contrary, feelings of worry or fear, pain or distress, and doubts about one’s ability to breastfeed can inhibit the reflex and prevent the flow of milk. Breast care should be done before each feeding in four steps: warm compresses: apply a hot towel to the breasts for 2-3 minutes; patting: pat gently in a clockwise direction for 2-3 minutes; massage: use the big or small fishbone of your hand to massage in a clockwise direction from the outer quadrant of the breast. Massage each breast for 2-3 minutes; Shake: hold the nipple and shake it for 2-3 minutes. After this treatment, squeeze the areola and nipple in a separate pinch with the thumb-forefinger towards the sternum and the milk will be discharged smoothly. When breastfeeding to prevent the breast a large and small, in each breastfeeding to eat one side and then eat the other side, the next breastfeeding to rotate. If you suckle the left side first in this feeding, you should suckle the right side first in the next feeding, so that each side has time to empty, equal lactation, and the two sides will be the same size. If you always eat only this side first, this side of the lactation is more and more, the breast will be more and more large, the formation of bilateral breast size is not the same. Breastfeeding can also cause nipple cracking, which is mainly caused by the baby’s incorrect position when sucking the milk. The baby should not only contain the nipple, but most of the areola and nipple. After eating the milk, the new mother herself and then squeeze out some milk on the nipple, which will not cause nipple cracking, nor will it cause the baby sucking when the mother’s nipple pain. Some new mothers like to lie down to breastfeed, when the breast pull is relatively large. Especially babies fall asleep after sucking milk, should develop the habit of sucking milk after the tugging out of the nipple, do not suck on the nipple to sleep. After breastfeeding, you should bring a cotton, suitable bra, which can play a supporting role for the breasts and avoid breast sagging due to breastfeeding. Before and after breastfeeding should be on the breast massage, massage is to promote breast health and beauty of an effective method, massage can effectively stimulate the breast, increase local blood circulation, promote breast development, prevent breast sagging, so that the breasts become plump and elastic. Generally we first clockwise, then counterclockwise, two-way alternating massage, to the skin slightly red and hot, such as conditions can be combined with the massage of the breast effect is better. During the month can eat more food containing gelatin protein and cholesterol, conducive to milk and breast development. Such as: pig’s trotters, cow’s trotters, chicken claws, chicken wings, turtle and animal protein, these foods will make the breasts solid. Vitamin A, B, E has the role of promoting breast development, containing vitamin C foods, such as fruits, vegetables can make breast health.
