It is not possible to generalize how often babies should be fed, but the interval usually ranges from 1 hour to 5 hours. The interval between breastfeeding for infants varies slightly depending on the baby’s own condition and the period of time in which the baby is born, with premature babies generally needing to be fed for about an hour. Breastfeeding for babies should be done on demand and at the same time, the feeding time should be taken into consideration. For full-term babies, feeding can usually be done once every 2-3 hours during the day, and the night interval can be extended to once every 4-5 hours. In addition, when the baby is 4~6 months old and starts to add complementary foods, the feeding interval can also be extended appropriately. It should be noted that when the baby has a decrease in the amount of milk, it should go to the regular hospital to clarify the cause and be treated under the guidance of the doctor.
