The lowly printable coloring page is really a chance to show kids a lot of things about the world and best of all you can find coloring pages on just about every theme and idea and they are often free to print out. Printable coloring pages even work well in a pinch. If you have a bunch of kids over and only one unused coloring book left, it's easy enough to go online and print out as many copies of coloring pages as you need.
In the context of Winnie the Pooh coloring pages, many parents are a little hesitant to purchase them on the basis that they are a finite resource, in other words, once they have been colored in they will no longer provide any (or at least the same) degree of entertainment and pleasure as they did previously. From a economic/capitalist perspective, such concerns are perfectly understandable, although like anything else in the world, in order to reach a more balanced and accurate conclusion it is necessary to consider all of the different variables that are in play.
Show a genuine interest in their "masterpieces" and set aside some time to discuss their work. Christmas coloring pages can instill a confidence in a child that they'll carry with them as they enter school and begin their journey into adulthood.
