A 1-month-old newborn baby with symptoms such as indigestion can use Bifidobacterium bifidum as prescribed by the doctor. Bifidobacterium bifidum is a kind of probiotic bacteria in the intestinal tract, which can improve the intestinal environment, inhibit harmful bacteria, and resist pathogen infections, etc. Moreover, the short-chain fatty acids produced by Bifidobacterium bifidum can stimulate intestinal peristalsis to effectively improve constipation, diarrhea and other symptoms. If a one-month-old newborn baby suffers from bloating, diarrhea, constipation and other symptoms of indigestion, Bifidobacterium bifidum can be used to improve the discomfort caused by improper diet. Although Bifidobacterium bifidum can be eaten by newborns, it needs to be used under the guidance of a doctor, and should not be taken on its own, and if the baby is in discomfort, it should seek medical treatment in time.
