Kangaroo Plus Ltd, a neonatal innovation dedicated to saving preterm and low birth weight babies, has benefited from a dynamic collaboration with Design without Borders Africa. Through an engaging, human-centered design process, the team refined the Kangaroo+ jacket, enhancing its functionality and sustainability. This low-cost solution not only provides essential warmth but also features a temperature monitor that lights up red and buzzes to alert mothers when a baby experiences hypothermia—a critical advancement for Uganda, where high-tech options like incubators are scarce. The World Health Report highlights that one million babies die annually due to prematurity and low birth weight, underscoring the urgency of this work.
