Newborn babies can be breastfed within 15 minutes – 2 hours after birth. Early initiation of breastfeeding and breastfeeding on demand Sucking is the key point and initiating force to promote lactation. Sucking is the main conditioned stimulus and should be initiated as early as possible (within 15 minutes-2 hours after delivery). Early initiation of breastfeeding can reduce physiologic jaundice in infants, and also reduce physiologic weight loss and hypoglycemia. Small infants aged 0-2 months breastfeed several times a day, on demand, so that the sucking is strong, the nipple is stimulated several times, and milk secretion increases. Powerful sucking causes prolactin to maintain a high concentration in the blood. The afferent nerves of the areola are particularly sensitive during the 2 weeks postpartum, and the conditioned reflex to induce the secretion of prolactin is easy to establish, which is a critical period for establishing breastfeeding. Correct feeding techniques include stimulating the infant’s oral dynamics, which is conducive to sucking; arousing the infant’s optimal state of breastfeeding (awake and hungry), and allowing the infant to push against the nose or lick the mother’s breast with the tongue before breastfeeding to adopt the most appropriate breastfeeding position, so that the mother and the infant both feel relaxed. Breastfeeding is the best choice for both the child and the mother. Successful breastfeeding requires not only healthy physical preparation but also positive psychological preparation. Pregnant women should understand the benefits of breastfeeding as early as possible, increase their willingness to breastfeed, and learn the methods and techniques of breastfeeding in order to prepare for the early initiation of breastfeeding and successful breastfeeding after delivery.
