This has to be the closest thing I have ever seen to the sale of bottles of fresh air. As a recent first time Dad I know that a new parent is prepared to try anything to help their baby sleep. My wife and I did a bit of research and found that some people have found that white noise has helped babies go off to sleep.
Interesting thought I, might as well give that a go. To my astonishment I found that there are web sites out their selling CDs of white noise.
Here are a couple of examples (lots more out there).

Wow what a bargain 12hr mp3 of white noise for only $9.99! Well how about getting white noise for free, at any volume you want, for as long as you need?
If you want to try out white noise with your baby, or know friends who might be thinking about it then bear this in mind. To get white noise all you need is an FM radio, knock the tuner off station, and hey presto white noise. Please don't go giving these gits any money.
