How did Johann van Beethoven try to promote his son as a child prodigy?

Johann van Beethoven recognized his son’s talent for the piano at an early age and attempted to promote him as a child prodigy, specifically modeling his efforts after the success of Wolfgang Amadeus Mozart.12

However, these efforts were ultimately unsuccessful, and Ludwig did not begin to attract significant attention until his adolescence. While his father’s initial attempts to manufacture a prodigy did not yield the desired results, Beethoven’s musical development was later fostered through his formal training as an assistant to the court organist Christian Gottlob Neefe and his eventual studies with Joseph Haydn.12
