Before positioning an infant or child's airway, you should:

Positioning an infant or child correctly before addressing their airway is critical for ensuring that the airway is clear and accessible. Placing the child on a firm surface is essential because it provides stability and helps maintain an open airway. A firm surface allows the caregiver to effectively manipulate the head and neck to align the airway properly without the risk of the child sinking or shifting during the procedure.

When dealing with pediatric patients, their airways can be anatomically different from adults, often requiring different positioning to maintain patency. Laying a child on a soft or uneven surface could lead to airway obstruction or hinder the effectiveness of any interventions. Thus, starting with a firm surface lays the groundwork for safe and effective airway management.
