Generally speaking, it is safer for babies to drink yogurt after the age of 2. If some parents want to try yogurt for their one-year-old babies, it is not a bad idea. However, it is important to pay attention to the right amount and not to give too much at a time. Although yogurt contains probiotics that are beneficial to human intestinal health, the probiotics contained in yogurt are different from those in the baby’s intestinal tract; the gastrointestinal microflora of a one-year-old baby is in a stage of growth and change and is not yet stable, so too much yogurt may lead to imbalance in the ecological balance of the original microflora in the intestinal tract, destroying the intestinal flora and affecting normal digestive function, which may cause diarrhea. This may cause diarrhea, which is especially bad for infants with gastroenteritis and premature babies. In addition, many varieties of yogurt in the market have added food flavoring to increase the taste, which can often make babies with developing sense of smell have deviations in taste, picky and anorexic, and even affect the growth and development of babies. Although yogurt is made from milk, it is not a substitute for formula, let alone a regular meal, and the protein and calcium content of many yogurt dairy products is not as good as it should be. Therefore, it is not recommended that babies within one year of age consume too much yogurt.
