My son is 6, almost 7, and we have had the Wii for alittle over a year and he loves to play it. This past year, just before Christmas time, I noticed that during conversations, the thing he would want to talk about the most was the Wii games. He was way wrapped up in Mario Galaxy and all the worlds and such. I decided that too much of his brain power and thoughts were revolving around video game (aka non-real) things. His play was already limited, but what I did and still do is limit his play to weekends only. During the week I do let him play a few computer games, but Wii is only for weekends that way he is forced to still do other play such as drawing or Legos that he loves.
