Breastfed newborns generally have about 2-4 bowel movements per day, while formula-fed newborns generally have about 1-2 bowel movements per day, but there are individual differences. Breastfed newborns due to the high content of prostaglandins in the mother’s milk, lactose, fat content is also high, the baby’s stools are more frequent, about 2-4 times a day stools, mostly golden-yellow soft stools, slightly sour odor. Formula-fed newborns have about 1-2 stools per day. There is no prostaglandin in milk powder, which can not promote intestinal peristalsis, while the lactose content is relatively low, casein and minerals in milk powder are also prone to cause constipation, resulting in the child’s stool less frequently, 1-3 times a day, hard texture, into a pile, heavier odor. There is no obvious pattern of newborns’ stools, and the number of stools varies greatly among individuals, with some having more money and some having less, but if the newborn’s diet, sleep, spirit and other aspects are normal, and his growth and development are good, it’s usually normal. Newborns try to breastfeed, if the child’s stool frequency is more than the usual obvious abnormalities, please go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, to give targeted treatment.
