The key to a successful exam of a toddler or preschool-age child is building rapport and trust between them and the provider. Toddlers, in particular, may be wary of strangers and unwilling to cooperate with the physical exam, which is expected age-appropriate behavior. In order to provide good care and create a comfortable patient experience, clinicians need to tailor their interaction to the child's developmental...
