When my daughter was a baby, I used gripe water and it worked well most of the time. It also helped when the baby was constipated.
I found out about the benefits of gripe water for infants when I visited my pediatrician. My baby was gassy and fussy so the doctor recommended gripe water. She also said that light syrup diluted in water also help with stomach discomfort. She told us that the sugars help settle a baby's stomach because they are easy to digest. She said that this is why most gripe waters are like a light syrup.
