Children with severe cerebral palsy and particularly those with oropharyngeal dysfunction are at risk of poor nutritional status. Determining the need and the mode of nutritional intervention is multifactorial and requires multiple methodologies. First-line treatment typically involves oral nutritional support for those children who are safe to consume an oral diet. Enteral tube feeding may need to be considered in children with undernutrition where poor weight gain continues despite oral nutritional support, or in those with oropharyngeal dysphagia and an unsafe swallow. Estimates for energy and protein requirements provide a starting point only, and ongoing assessment and monitoring is essential to ensure nutritional needs are being met, that complications are adequately managed and to avoid over or under feeding.
