What physical sign may indicate that a toddler is experiencing separation anxiety?

A toddler exhibiting separation anxiety is often characterized by distress when a primary caregiver leaves the room. This distress can manifest as screaming, crying, or clinging to the parent. The behavior is a natural response to the fear of being away from the parent, demonstrating the child's attachment to their caregiver and their struggle to cope with being apart.

In contrast, smiling and waving indicates comfort and understanding that the parent will return, which does not align with the signs of separation anxiety. Similarly, playing cooperatively without concern or independently engaging with a nurse further suggests that the child is secure and unbothered by the absence of their caregiver. These behaviors signify confidence and a healthy sense of exploration, rather than the anxiety commonly associated with separation from a primary caregiver.
