If a child eats milk powder and has a white tongue, the main reason is that the milk powder is causing the child’s tongue to be stained with moss. At this time, except for the white tongue, the child’s mental state and diet are normal, and the child does not have symptoms such as crying and restlessness, or undigested milk flaps in the stool; this is a normal staining of the tongue and parents need not worry too much. If the child not only has a white tongue, but also has symptoms such as bloating, abdominal pain, and undigested milk flaps in the stool. Parents can massage the child’s stomach clockwise to promote the discharge of the accumulated food; if the symptoms are particularly severe, parents need to apply medication to the child. For example, Baohe Pill.
