Research has found that certain probiotics can help infants pass stool more easily and reduce symptoms of constipation. Probiotics are live bacteria and yeasts that are beneficial for our health, especially for digestion. When given to babies, probiotics can help to restore the balance of good bacteria in their digestive system and reduce the symptoms of constipation. However, it is important to note that probiotics should only be given to infants under the advice of a doctor.
