A 2-month-old baby, born at 38 weeks, is brought in due to increasing fussiness around 30-60 minutes after feeds, frequent regurgitation, ‘colic’ episodes, and non-bloody diarrhea. The baby has not experienced fever, urticaria, angioedema, or wheezing. The baby is exclusively formula-fed and has mild eczema in the flexural areas. The baby’s weight remains stable between the 50-75th centile. What is the most appropriate next step in managing this baby’s symptoms?
