You can also give the baby some dosage that Mommy loves: half a bag two or three times a day+half a bag of Smith Damon ToxoSmithKline powder two or three times a day, and the baby will be fine in about 3-5 days. You can also eat some apple puree: apples are also alkaline foods, containing pectin and tannic acid, which have the functions of adsorption, convergence and diarrhea. Take a fresh, soft apple, cut it in half and scrape it into mud with a spoon.
