Childhood is a time of significant velocity in growth. Growth predicts health and well-being and currently acts as one of the most valued measures of how a child is developing. When growth fails to occur at a time and rate that is expected, children are perceived to require additional support and interventions to help minimise the risk of malnutrition, dehydration and mortality. Faltering growth is often considered difficult to identify. Nurses both in community and hospital settings need to be equipped with skills to assess growth of infants and children, supporting early intervention strategies. This article explores the many aspects for consideration that can guide efficient faltering growth assessments.
