Children's food stagnation is primarily due to excessive dairy and food intake, which damages their spleen and stomach, causing the dairy and food to stagnate in the middle burner and leading to a series of gastrointestinal disorders. When children experience food stagnation along with a cold, the symptoms mainly include decreased appetite, excessive phlegm, persistent cough, nausea and vomiting, bad breath, abdominal bloating and pain, foul-smelling stools, constipation or diarrhea, heat in the palms and soles, a more irritable temperament, and a tendency to cry easily, among others.
