Correct answer: E — Food protein-induced allergic proctocolitis (FPIAP)

Blood-streaked stools in a well, thriving breastfed infant is the classic presentation of food protein-induced allergic proctocolitis (FPIAP). It is a non-IgE-mediated reaction, most commonly to cow's milk protein in the maternal diet. Management involves maternal elimination of cow's milk protein with reassessment. Most infants outgrow it by 12 months.
