Abstract
Gastrointestinal conditions that can cause feeding issues in infants – such as colic, gastroesophageal reflux and gastroesophageal reflux disease, cow’s milk protein allergy and lactose intolerance – can be challenging to differentiate because of symptom overlap. This article describes these conditions, outlining similarities and differences, and details how to conduct a comprehensive assessment of infants with feeding issues related to gastrointestinal conditions to support their accurate diagnosis and timely management. The importance of developing positive relationships with parents and working in partnership with them to help them understand their child’s condition and manage their child’s symptoms is emphasised.
