What are the potential clinical causes for an 18-month-old toddler presenting with acute solid food refusal, irritability, a resolved low-grade fever, and a newly developed productive cough, and does cow's milk consumption medically contribute to increased phlegm production?
These symptoms, including the cough and temporary food refusal, are very common with mild viral respiratory infections or teething, which can make their throat sore. Please be reassured that medically, cow's milk does not actually produce more phlegm, though it can temporarily make saliva feel slightly thicker. For now, focus on keeping her hydrated with fluids like water or milk, and offer soft, easy-to-swallow foods. Please consult her pediatrician.
