If a one-year-old baby has indigestion, first we should pay attention to the child's diet to see if it is normal. A one-year-old child should ideally have three main meals a day and then drink about 500ml of milk or formula. If the child's diet is inappropriate, or the child has little physical activity, or due to illness, etc., these can lead to indigestion. In such cases, we first need to adjust the dietary structure, offering the child light and easily digestible food, and avoid foods that are too fatty or too sweet. Additionally, some medications for treating indigestion can be administrated to the child, such as gastric protease granules, multi-enzyme tablets, pediatric fel nigrum extract, etc. For children who also have abnormal stool, probiotics can be given to help regulate their digestion.
