A. Persistent separation anxiety
Persistent separation anxiety may suggest an emotional problem in a 3-year-old child. It can manifest as excessive distress or anxiety when separated from a caregiver or reluctance to engage in activities without the caregiver. This behavior may indicate that the child is experiencing difficulties with emotional regulation or attachment.
Examples of other behaviors that might suggest an emotional problem in a 3-year-old child include sudden mood swings, difficulty sharing toys or interacting with others, or engaging in self-soothing behaviors such as thumb sucking. It is important to observe and assess the child's behavior in a comprehensive manner to get a better understanding of their emotional well-being.
