Allowing the toddler to explore and handle the equipment, such as a stethoscope or blood pressure cuff, can help familiarize them with the objects and reduce anxiety. It can be done under the supervision of the nurse to ensure safety.

Starting the examination with routine immunizations can be helpful because it allows the child to get through potentially uncomfortable or distressing procedures early on. It can also create a positive association between the examination and a sense of relief after receiving vaccinations. While it is important to provide age-appropriate explanations to the toddler, it's essential to keep the explanations simple and concise. Using child-friendly language and demonstrating the procedure using dolls or toys can help the toddler understand what will happen during the examination.

Instead of completely undressing the toddler, it is generally more comfortable and less distressing to only partially undress them. For example, the nurse can ask the caregiver to remove the toddler's shirt while leaving the pants on. This approach helps maintain the child's sense of security and provides a level of modesty.
