Which of the following personality types is NOT common among infants and toddlers?

The personality type that is not commonly observed among infants and toddlers is reserved. Infants and toddlers are generally in a critical stage of social and emotional development where they are learning to interact with their environment and the people around them. At this stage, babies usually display a range of expressive behaviors and are often eager to explore, make connections, and engage with caregivers and peers.

While some children can exhibit shyness or periods of quiet observation, the overall expectation is that infants and toddlers will exhibit more outgoing and exploratory behaviors. They are typically characterized by their ability to form attachments, show curiosity about new experiences, and express their emotions openly, making reserved a less common trait for their age group.

Friendly, fearful, and feisty behaviors, on the other hand, are relatively typical for infants and toddlers. They can be friendly as they engage with caregivers and others, fearful when confronted with unfamiliar situations, and feisty by demonstrating strong-willed or spirited behavior as they assert their preferences and desires. Each of these traits can be seen as part of typical development as children navigate their growing understanding of themselves and their relationships with the world around them.
