During phototherapy for newborn hyperbilirubinemia, which instruction is most appropriate for feeding?

• A. Feed newborn at least every 2-4 hours
• B. Breastfeeding should be discontinued until phototherapy is completed
• C. Make sure the newborn's eyes are closed when applying eye patches
• D. Keep the baby quiet and swaddled

Answer: (A)

Phototherapy can increase fluid losses in newborns, so maintaining good hydration is essential for helping bilirubin be excreted. Feeding at least every 2–4 hours keeps fluids up, provides calories, and promotes bowel movements, which help eliminate bilirubin through the stool. Continuing regular feeds supports this goal and is preferable to stopping breastfeeding during treatment. Eye protection is important during phototherapy, and keeping the baby comfortable matters, but the feeding schedule has the most direct impact on bilirubin clearance in this context.
