2. Yogurt is made by adding lactobacillus to fresh milk for fermentation, or adding lactic acid and citric acid. Yogurt has the same nutrients as fresh milk, and because of the increase of acidity, the protein clot becomes thinner and easier to be digested and absorbed. At the same time, the lactobacillus can inhibit the Escherichia coli in the intestine, so it is suitable for babies to drink, especially for infants with diarrhea. "However, there are still many lactic acid bacteria drinks on the market under the banner of yogurt. Lactic acid bacteria drinks contain very little milk, mainly water and some lactobacillus added, so their nutritional value cannot be compared with yogurt. Lactic acid bacteria drinks are not dairy products, but drinks. Lactic acid bacteria drinks cannot be used to replace the milk that babies need to drink every day. Therefore, when parents buy yogurt, they must recognize that it is an authentic yogurt product, not a lactic acid bacteria drink. "

3. In addition, experts remind parents: Because yogurt has a certain acidity, so don't give your baby too much every day, so as not to affect the normal pH in the gastrointestinal tract. Generally, after the baby 1 year-old, he can be given yogurt, and it is advisable to drink 1~2 small cups a day.
