In partnership with the Uganda Private Midwives Association (UPMA), MOMENTUM Private Healthcare Delivery combined a supply-side intervention—training and support for UPMA providers— with demand-side activities using human-centered design (HCD), to improve demand for, and uptake of postpartum family planning (PPFP). This brief describes the intervention and results of using demand creation prototypes to improve demand and use of PPFP. The brief is intended for FP program implementers seeking experiences of using HCD for PPFP demand creation in the private sector.
