In the early 1940s, World War II was ranging. A high priority for elders at the time was to get the minds of young children off the war (while urging boys in their late teens to get ready to fight). The psychology is similar to that of other "crisis" periods such as the Revolutionary and Civil wars. These comic characters served as "babysitters" (and role models) for young children at the time.

Woody Woodpecker was actually created in the 1930s and went through several changes before being presented to the public in his first cartoon short in 1940. His second carton, titled appropriately enough "Woody Woodpecker", had a higher level of energy and featured a jazzy musical score that apparently appealed to adult audiences. The fact that his cartoons were more outrageous, made people laugh, and featured rousing musical accompaniment no doubt contributed to his overall success.
Keep in mind that these cartoons were produced as shorts for showing in theaters, and not on television. Most of the movie going public during this time period was adults, and not children, so I believe you are incorrect in assuming that these cartoons were made expressly for children. Most American children would not actually be exposed to Woody until 1957 when he was first broadcast on television.
