The term "12-24 months" typically refers to a specific age range in child development. During this period, children experience significant growth in physical, cognitive, and social skills. They begin to walk, talk, and explore their environment more independently, which is crucial for their overall development. In various contexts, "12-24 months" can also indicate a timeframe for projects or plans. For example, businesses may set goals or milestones to be achieved within this period. This timeframe allows for adequate planning, execution, and assessment of progress in achieving desired outcomes.
