Infants are malnourished. If they are breast-fed, it is considered that milk in Ma Bao is not nutritious enough. In this case, Ma Bao should strengthen nutrition to improve the nutrition of milk, and the nutritional status of infants will follow.

If the baby has a poor appetite, it is necessary to enhance the baby's appetite. For example, the baby's appetite is poor because of zinc deficiency. We can give the baby zinc supplementation treatment in a standardized way, and we can also give the baby some Chinese patent medicines for invigorating the spleen and appetizing, such as Xiaoerkang granules and Xingpiyanger granules, which are acceptable.

There is also a case of chronic diarrhea for a long time, and this child will also be malnourished. For this kind of malnutrition, we need to find the cause of chronic diarrhea for children according to the primary disease and carry out targeted treatment. After the symptoms of diarrhea are corrected, the baby's nutritional status will also be improved.
