Your baby’s bowel movements will tell you a lot about their health, their diet, and how their stomach is doing. In order to detect when something is up, you will need to pay close attention to the daily occurrences and patterns. The color, consistency, and frequency are all important factors. Any sudden changes or inconsistency with their bowel movements may indicate illness. However, just making mental or written notes is usually enough.
