Description: Management of severe acute malnutrition (SAM) in infants under6 months has been poorly addressed. To contribute to fill in this knowledge gap the results of a nutritional rehabilitation program in Niger are reported. Study design: Presentation of a case series (n=632) of young infants who selfpresented to a nutrition rehabilitation program in 2010-11. Main characteristics of the inpatient treatment protocol were: diluted F-100 milk via the supplementary suckling technique until exclusive breastfeeding was re-initialized; coaching of mothers on infant feeding and intensive antibiotic therapy if indicated during stabilisation phase. Semi-structured interviews were also conducted with 103 mothers.
