Appropriate probiotics for babies can regulate the intestinal flora imbalance and improve gastrointestinal function. However, if applied for a long time, it may affect the normal establishment of intestinal flora, but cause gastrointestinal discomfort. 1. Advantages: baby eating probiotics can be beneficial to the regulation of intestinal flora, thus improving the baby’s gastrointestinal function, as well as improving the phenomenon of gastrointestinal dysfunction, and can inhibit the reproduction of harmful flora, which is conducive to the absorption of nutrients. 2. The bad side: But if the baby takes probiotics for a long time or often abuses probiotics, it may affect the normal establishment of the baby’s own intestinal flora, and if the drug is discontinued, it will instead lead to intestinal flora imbalance and induce gastrointestinal discomfort such as abdominal distension and diarrhea. Therefore, although probiotics have more benefits for the body, but it is recommended not to give the baby long-term as well as the abuse of probiotics, should follow the doctor’s instructions for medication, so as not to cause adverse effects on the baby.
