Most infants do not have stools for two days without any special abnormalities, because insufficient intake or too little exercise can lead to no stools. If the baby does not have vomiting, abdominal pain or bloating during the two-day absence of stool, it can be observed. At the same time, improve your baby’s diet, eat more food rich in coarse fiber, such as celery, spinach, fungus, appropriate amount of coarse grains, etc. Let your baby exercise moderately and massage clockwise around the belly button to promote bowel movement and defecation. If your baby has obvious abdominal pain and bloating during this period, go to the hospital in time to rule out congenital anal stenosis and other abnormalities.
