Art is an outlet. It's a a release from the pressures of school and life. Even young children experience this. Look up Art Therapy and you will find many places that offer it. Art therapy uses creativity to improve a person's physical, mental, and emotional well-being. We've read enough tragedies in the news to know. So, if giving my son a camera helps him work through his frustrations, that's the least I can do for him.
And let's face it, digital photos are cheap. He can take as many pictures of his legos, his toes, the wall, the ceiling, etc. as he like and he's not spending a fortune on throwaway images. And once in a while, there's a little gem in the many usual kid pictures. Eventually, those gems will increase in number as he realizes what he's doing and learns how to use the camera. Because he mimics me, he's already on his way to learning about photography. Also, as I've repeatedly said, the more you use the camera, the better you get at photography.
And it doesn't stop with just photography. Many times, he's asked if he could paint while I was painting. When the schools cut art from the curriculum, he didn't miss out because I encouraged artistic expression at home,. It does make me sad that other children will not get that opportunity, but I'm not getting on my soapbox about politics and school curriculum for this post.
If you haven't already, take a trip to your local Michael's or JoAnn's and let your child wander the aisles. One of the crafts or arts will capture their imagination. Let them explore it. If you don't know how to do that particular craft, there are plenty of beginner kits where both you and your child can learn and create together.
