A parenting intervention in Rwandan refugee camps aimed to improve early childhood development (ECD) and caregiving practices among families with children under five. Delivered in high- and low-dose formats, the program significantly improved caregivers’ engagement in early learning activities and responsive feeding, though it did not impact child development scores or caregiver mental health. These findings suggest that even low-dose parenting support can enhance nurturing care in humanitarian settings, helping build child resilience despite limited resources.
