Newborn babies can generally have seven or eight bowel movements, and most of them are black stools, which are fetal stools in the body. Newborn babies will have their fetal stools excreted within 3 days and their stools will start to change to golden yellow. When the fetal stool is completely expelled, if the baby is breastfed, the number of bowel movements per day is less than 6 times more appropriate, and at most the number of feedings should not exceed the number of breastfeeding. If a breastfed infant has more diluted stools or more frequent bowel movements, there is no need for parents to worry as long as the infant is full of energy, eats milk well, and has normal height and weight growth. Powder-fed infants should have no more than 3 bowel movements per day and at most no more than 6 per day. Above the range, consideration should be given to whether the baby has diarrheal disease. Parents should be aware that if the number of bowel movements suddenly increases, for example, from 3 or 4 times a day to 7 or 8 times a day, they should be alerted to the possibility that their baby is ill. Observe the number of stools, but also pay attention to the stool texture. If the stool is very thin, it is obvious that the stool is thin and watery. This is also an abnormal manifestation of diarrheal disease, and parents need to judge whether their child is in a normal state based on the number of stools and their traits. Common causes of increased stools or changes in stool traits in newborns include gastrointestinal infections, lactose intolerance, etc.
