What key language milestone is reached by a child at 1-1.5 years?

At 1 to 1.5 years of age, a significant language milestone that children typically achieve is the ability to name objects. At this developmental stage, children begin to say their first meaningful words, which often include the names of familiar people, common objects, or simple concepts. This ability marks the transition from non-verbal communication to verbal expression, enhancing their capacity to communicate their needs and interests.

This naming ability also reflects cognitive development, as the child begins to associate words with their meanings and can identify objects in their environment.

In contrast, while cooing is an earlier stage of vocalization that occurs around 2 to 3 months of age, it does not signify the beginning of language development characterized by naming. The skills of stringing words together or using two-word phrases usually emerge later, around 2 years of age, indicating more advanced language development that builds on the foundational ability to name objects.
