What should I do if my newborn has diarrhea for 20 days?

Patient's question:

Description: Past treatment and effectiveness: Test results: Newborn diarrhea

Doctor's answer:

Breastfed infants have loose stools because 80% of breast milk is water.
Generally, the stools of breastfed infants are yellow or golden yellow, with a uniform consistency like cream or paste. Occasionally, they may be slightly thin and greenish, with an acidic smell but no odor, and are excreted two to four times daily.
If an infant normally has only one to two bowel movements per day but suddenly has five to six, it may indicate illness. If bowel movements are frequent but the child is generally well and not losing weight, there is no cause for concern.
Breastfeeding can shorten the duration of each feeding session, allowing the child to consume only the first half of the milk. The first half of breast milk contains more protein, which is easier to digest and rich in nutrients, while the second half has more fat, which is harder to digest. If necessary, the mother can drink a large glass of diluted salt water half an hour to an hour before feeding to thin the milk, and then breastfeed the child.
