Neonatal Jaundice

Sarah Mitchell is a 4-year-old female presenting with yellow skin in newborn. I noticed my baby boy, Liam, started looking a little yellow on his face yesterday morning, around day 3 of life. By the evening it had spread to his chest and tummy, and now today on day 4 it looks like even his arms are turning yellow. His eyes look yellow too. Your task is to take a focused history from this patient.
