Newborns who have not had a bowel movement for two days need to choose the appropriate measures according to the cause of the disease. Common causes are low milk intake, constipation and congenital megacolon. If the milk intake is normal, you can massage the baby’s stomach clockwise, or take probiotics such as bifidobacteria to adjust the intestinal flora if you consider intestinal flora imbalance. If the newborn continues to have no bowel movement for a long period of time, it is recommended to go to the hospital in a timely manner to clarify the cause of the disease. 1. Too little milk: newborns due to the intake of too little milk. As a result, feces cannot be formed, and the situation of not having a bowel movement for two days will occur.
