1-3 months babies should be breastfed on demand, 2nd month babies should be breastfed more than 8 times a day, the total amount of breastfeeding per day can be calculated as 100-150ml/kg. In general, for full-term normal weight babies, the total amount of breastfeeding per day can be calculated as 100-150ml/kg. At each feeding, babies suckle at one side of the nipple for 10 minutes and then switch to the other side of the nipple to suckle for 15 minutes. Newborns are usually breastfed 8-10 times every 24 hours. After 3 months, infants are gradually regularized in their breastfeeding intervals, and are fed once every 3-4 hours at 4-6 months of age. Breastfeeding is more difficult to estimate the amount of milk fed, when the baby has normal weight gain, sleeps well and urinates 6-7 times a day, it proves that the amount of milk is sufficient. If the baby has a decrease in milk intake and is reluctant to eat, it is necessary to clarify whether there is a pathological factor, and it is recommended to consult a medical professional for guidance on breastfeeding.
