A 3-day-old male infant presented to the emergency department for jaundice. He was born at 39 weeks of gestation via spontaneous vaginal delivery, with a weight of 3,056 g and Apgar scores of 8 and 9. The mother was 35 years old, and this was her second child after an uneventful pregnancy. He was breastfed 10 times per day, with 4 daily diaper changes. On examination, his vitals were normal, and he interacted well. He had icteric skin over the face, trunk, and legs, with subtle hyperpigmentation of the axilla and scrotum (Figure 1).
