We first had the idea about creating co-sleeping diagrams when we spoke about how little sleep we both got. Each of us co-slept to varying degrees but anytime our babies slept on or near us, we noticed how utterly uncomfortable we were. Once Andy, a designer, thought of drawing a birds-eye view the ideas exploded out of our mouths. We now have a list two pages long of every conceivable and inconceivable body position. We also get a ton of submissions from readers telling their best/worst sleep position which is always a gas. Our favorite thing about these diagrams is the user-interaction. People are so ready to tell you how little sleep they got and the new, strange position they found themselves in. It's like a co-sleeping support group by email and blog comments.
