Twelve US sites will begin enrollment in early 2026 to accomplish three core activities (CA). In CA1, we explore infant feeding decision-making and experiences via in-depth interviews with pregnant\/postpartum WLHIV (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200950), their partners and other influential individuals (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200925), and a diverse sample of healthcare professionals (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200945). Site-level surveys assess infant feeding practices and estimate the prevalence of breastfeeding among WLHIV. In CA2, we establish an observational longitudinal cohort of 450 WLHIV-infant dyads to examine infant feeding practices and outcomes. WLHIV will be enrolled during pregnancy and early postpartum, with half intending to breastfeed, and will be followed for \u226548 weeks. Clinical and laboratory data will be collected. Comprehensive surveys collect data on demographics, social determinants of health, mental health, antiretroviral therapy adherence, and infant feeding intentions and experiences. We measure HIV RNA and DNA in breast milk to determine factors associated with detectable HIV. Finally, we estimate the costs and benefits associated with breastfeeding compared to replacement feeding. In CA3, we develop and pilot a voluntary registry of U.S. WLHIV who are breastfeeding and their infants (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200950\u2212200).
