Warning, this may sound dangerous However I will do everything needed to make sure what you are probably thinking WON'T happen . I can't find much sun in my yard during winter months. My idea-I get lots of sun in the front of my house, but I have no front yard. I live on the third floor of my three flat. I was thinking about building a mini green house onto a platform. The platform will have sides on it. I would stick the greenhouse end of the platform out my window in the sun. The other end of the platform will be inside my house. He could get some warm sun rays and nibble on plants etc, that I would grow in the green house and be able to come inside the house to get cooled off and into shade. I would have the green house fit the width of the window, so cold air could not come in. I would also make sure the whole thing could not fall out the window, even if the window were to be opened all the way. Any thoughts, pros or cons, ideas, suggestions wanted. Oh ya, this would be for while he is still small enough for it to work. I will have to come up with another plan when he gets to big. I would really like him to get some natural sunlight, even though he has a MVB.
