From 18 to 24 months of age, children develop which of the following skills?

At 18 to 24 months of age, children experience significant growth in their language skills, which includes the ability to define and express emotions with words. During this developmental stage, toddlers begin to expand their vocabulary and can articulate basic emotions such as happy, sad, or angry. This ability to use language to label feelings is an essential milestone as it aids in their social interactions and emotional understanding. By starting to communicate their feelings verbally, children are also learning to recognize and understand their emotions and those of others, which is crucial for their social development.

The developmental focus during this age is primarily on language acquisition and emotional expression rather than memorization of songs, screen time, or understanding complex narratives. It's a period characterized by the blossoming of communication skills that plays a vital role in how children interact with their environment and develop relationships with caregivers and peers.
