How is normal bowel movement for a 50-day-old baby (Figure)

Patient's question:

No

Doctor's answer:

1. Feces with a sour smell and excessive foam: This is because excessive consumption of carbohydrates, such as sweet sugar water or milk, leads to a relative deficiency of enzymes in the infant's gastrointestinal tract, causing the ingested food to ferment vigorously in the intestines and produce gas, resulting in feces with a sour odor and abundant foam. In this case, sugary foods should be avoided.
2. Curd-like and egg-like stools: The stool is loose and resembles egg fragments, occurring 5-6 times daily. This is due to poor digestion of protein and fat. In this case, the duration and amount of breastfeeding should be reduced.
3. Greyish-white, loose, or pasty stools, appearing shiny like cream: Occurring 3-4 times or more daily, this is often caused by excessive consumption of greasy foods. The reason is the high fat content in milk and a lack of digestive enzymes in the intestines, as the last part of breast milk contains more fat. Therefore, the breastfeeding time can be shortened, and it is best to avoid letting the infant drink the last part of the milk.
