Question
A four-month-old baby experienced a single dry vomiting episode six days ago. The doctor diagnosed it as indigestion and prescribed a stomach-soothing and digestion-promoting oral liquid. After treatment, the symptoms subsided. For the past six days, the baby has only been fed breast milk, has not had a bowel movement, and the stool is abnormally smelly and firm. The baby has undergone clockwise massage therapy. What should be done next?
