Full-term babies can take probiotics under the guidance of a doctor, but it is not advisable to give babies long-term probiotics. Probiotics can regulate the micro-ecological environment of the baby’s gastrointestinal tract, promote gastrointestinal dynamics, and enhance the immunity of the baby’s bodily functions and so on. When the baby has indigestion, diarrhea, intestinal flatulence, vomiting and other symptoms, you can use probiotics under the guidance of the doctor to improve the body’s discomfort. If the baby’s body has no symptoms of discomfort, the use of probiotics is not recommended. In addition, probiotics should not be used for a long period of time. Prolonged use of probiotics may have an impact on the intestinal flora and the normal barrier protection function of the intestines, which is not conducive to the health of the body. Full-term babies need to use probiotics under the guidance of a doctor, who will determine the dosage of probiotics and the course of use by a professional doctor to ensure the safety of the medication.
