Why your 3 months old baby stools are green color?

Green stools in a 3-month-old baby can be caused by various factors, including the type of formula they are consuming or dietary changes if breastfeeding. It may also be due to the baby digesting more bile, which is naturally green. In some cases, green stools can indicate a rapid transit through the intestines, often linked to a mild gastrointestinal upset. However, if the green stools persist or are accompanied by other symptoms, it’s advisable to consult a pediatrician.
