What findings would suggest breastfeeding failure jaundice?

Breastfeeding failure jaundice typically arises from insufficient feeding, which can lead to dehydration and inadequate bilirubin clearance. When a newborn is not receiving enough breastmilk, it can result in signs of dehydration such as reduced urine output, which is a key indicator of inadequate intake. Normal feeding patterns should contribute to proper hydration, bile production, and the excretion of bilirubin through the stools; thus, when dehydration is observed alongside a lower urine output, it strongly suggests that the baby is not getting sufficient breast milk.

In this context, the other options do not align with the characteristics of breastfeeding failure jaundice. Normal examination findings with adequate feeding would indicate healthy breastfeeding practices, while excessive weight gain and normal stools would suggest that the infant is feeding well. Swollen labia and breast hypertrophy are typically unrelated signs and do not provide insight into breastfeeding efficacy or jaundice development. Therefore, the presence of dehydration and decreased urine output is a crucial finding suggesting breastfeeding failure jaundice.
