Improve dietary habits: babies who have not pooped for two days but only farted may be caused by drinking too little water, and need to give babies appropriate intake of water to promote the discharge of stools. 2. Use of medication: babies who have not had a bowel movement for two days and only fart may also be constipated, you can take probiotics, such as bifidobacteria, according to the doctor’s instructions, which can promote intestinal peristalsis. If there is a feeling of defecation, but can not pass stool, then you can use the open plug to promote defecation. 3.
