Training materials regarding feeding small babies have recently become available (Preterm infant feeding and growth monitoring: Implementation of the INTERGROWTH-21st protocol; Global Health Training centre (link is external)). However, we are not aware of a previous systematic review of the evidence that underpins practice in this area. Dr. Abimbola, Ibadan, Nigeria, will lead a systematic review with support from the co-investigators to evaluate the strength of current evidence and identify evidence gaps that could be addressed through future research by the network.
