Summary: The IYCN Project developed a job aid with a checklist to help health workers support HIV-positive breastfeeding mothers to decide if they can provide a nutritionally adequate and safe diet without breastmilk at 12 months. The checklist consists of two sets of questions: (1) questions on the child’s health and household food security, and (2) questions on current practices related to a minimum replacement diet. The job aid includes key points for health workers on how to counsel mothers depending on the result: either how to safely stop breastfeeding or to continue breastfeeding and antiretroviral medications, as well as instructions on how to use the job aid.
