When I was a young lad not a lot older than my son is now, I began using coloring sheets as an activity I could do with my father. I really enjoyed working on them but I also enjoyed the one on one time with my father and having something we could do together. So you can imagine how keen I am to continue this tradition and now begin having fun with my boy and some coloring pages.
When a child sits down for a coloring session they should be given free rein to express their own personal concepts, allowing their personality and attitudes to shine through. It is fine to help the child learn how to used coloring tools, but when you step aside and let them apply their own special touch to a coloring page, they'll discover a sense of who they are and it will jump start their appetite for knowledge.
If you have a little girl in your family then she is probably similar to my niece in that she wants to be a Princess when she grows up. I suspect it's down to all the Disney films she has watched religiously since she was very young. I haven't the heart to tell her that unless she marries a Prince soon she hasn't much chance. And no, I certainly don't know any royalty!
