There have been many peer reviewed published scientific studies that have shown the benefits of probiotics when added to the diet. Studies of probiotics have shown benefits to infants, babies and children as well as adults. Some studies have shown that probiotics can specifically ease symptoms in colicky babies, including reducing crying time. Probiotics are meant to be taken on a regular recurring basis, often daily. Probiotics work over time to support overall digestive health and immune function. Thus probiotics will not bring immediate relief to a colicky baby but may reduce the frequency and severity of bouts over time.
