Abstract
<jats:p>Kidney disease in children is relatively rare, making up just 5% of the end‐stage renal disease population. Paediatric nephrology dietitians have a key role in the multidisciplinary team to ensure effective care for patients. In children with kidney diseases, an assessment of growth and nutritional status is important to guide individual dietary prescription. The incidence of acute kidney injury (AKI) in children remains largely unknown, and it is likely that early AKI often goes unrecognised. Nutritional management of AKI can be complex; the dynamic nature of AKI requires frequent review and adjustment to plans, and close collaboration with the medical team is always vital. All children require regular monitoring of nutritional status, growth, biochemistry and fluid status, as their nutritional care plan is likely to require adaptation as their chronic kidney disease progresses or, in the case of AKI, their function hopefully improves.</jats:p>
