In a breastfeeding infant with colic symptoms, what is the first step to pursue?

• A. Empiric treatment with a proton pump inhibitor medication
• B. Eliminating certain foods from the mother's diet
• C. Stopping breastfeeding and beginning a hydrolyzed formula
• D. A complete work-up

Answer: (B)

The key idea is to start with a noninvasive, targeted approach that tests whether the infant’s symptoms are tied to the mother’s diet. In a breastfed baby with colic-like crying, removing potential dietary triggers from the mother's intake is the most sensible first step. Cow’s milk protein can pass into breast milk and may irritate a susceptible infant, so trying an elimination diet—most importantly dairy, and sometimes soy—for about 1–2 weeks helps determine if the symptoms improve. If the infant’s crying lessens, that supports a dietary link and you can plan the next steps, including cautious reintroduction of eliminated foods to confirm the cause. If there’s no improvement, or if red flags appear such as poor weight gain, vomiting, fever, bloody stool, or lethargy, then a broader evaluation is warranted and a different feeding plan may be considered. The other options—starting a proton pump inhibitor, stopping breastfeeding to switch to a hydrolyzed formula, or performing a complete work-up from the start—are not appropriate first steps for typical colic, which is usually a benign, self-limited condition managed with conservative, family-supported strategies.
