A 6-month-old baby boy is being evaluated. Two weeks ago, a trial of alginate therapy (Gaviscon) was initiated for frequent regurgitation accompanied by discomfort. Unfortunately, there has been no improvement in the symptoms, and the mother now reports that the baby is refusing to eat. There are no other new symptoms, such as a rash or diarrhea, and the baby is gaining weight steadily. He is exclusively bottle-fed, as his mother stopped breastfeeding at 8 weeks of age. What is the most appropriate course of action for managing this situation?
