What age range is associated with the toddler developmental stage?

The toddler developmental stage is recognized as encompassing the ages of 1 to 3 years. This period is characterized by significant growth and development in various areas, including physical, cognitive, and social-emotional domains. During this stage, toddlers experience rapid physical changes, including increased mobility as they learn to walk, run, and climb.

Cognitively, toddlers begin to engage in symbolic thought and develop a greater sense of autonomy. Language skills also begin to flourish, with toddlers often expanding their vocabulary and starting to form simple sentences. Additionally, social-emotional development includes the emergence of independence and willfulness, as toddlers explore their environment more actively and express a range of emotions.

This age group lays a critical foundation for future developmental stages, influencing social interactions, identity formation, and the ability to navigate relationships with peers and caregivers. The characteristics and milestones of this stage delineate it clearly from the other age ranges provided in the question.
