There is no strict limitation on the amount and interval of breastfeeding on the first day of a newborn’s life. It is mainly related to the newborn’s weight at birth, the amount of milk and other factors, and the principle of breastfeeding on demand should be followed. If the newborn weighs less at birth and has a smaller stomach capacity, he or she may eat less milk and the interval may be shorter, requiring on-demand breastfeeding, which is performed when the newborn is hungry. If the newborn weighs more at birth, he or she may eat more milk. You can tell if he or she is full by observing the newborn’s behavior. If the breast milk is large enough for the newborn to get enough at one time, the time between feedings will be long, and if the milk production is insufficient, the time between feedings will be relatively short. The first day of newborn feeding, pay attention to observe the newborn’s response, if choking, vomiting and other symptoms, to communicate with the doctor in a timely manner, under the guidance of the doctor scientific feeding.
