At what age is a child expected to show some understanding of the concept of 'no'?

A child is expected to show some understanding of the concept of 'no' around 12 months of age. At this developmental stage, infants are beginning to comprehend simple commands and can react to their environment based on verbal cues. They are typically able to recognize familiar words and understand basic terms related to their everyday experiences.

Showing understanding of 'no' is part of important cognitive and social developments. Children at this age might demonstrate their understanding by stopping a behavior when they hear 'no' or showing signs of recognition through facial expressions or changes in their actions. This understanding signifies an emerging awareness of social interactions and boundaries.

As children grow, their comprehension and response to social cues continue to develop. By 15 months, they may have a broader understanding and might be able to consistently respond to 'no' appropriately, but recognizing the command begins to take shape around the 12-month mark.
