This Sleep Sound is a 55 minute recording of a real live cricket.

Mr Cricket - as we'll call him - came visiting my home one night in January 2016. He decided to make himself known late in the evening when he started to chirp away in my laundry.

I immediately thought "what a great sound - I wonder if it would work as a Sleep Sound", so I very quietly crept into the laundry with my recording equipment and started recording - and he kept chirping for nearly an hour.

If you listen to the Sleep Sound recording yourself, you'll actually hear in the background, at about the 16 minute point, my son Alexander starting to cry for a few seconds, before he falls back asleep again. Alexander was in the family room, in his rocker at the time, fast asleep listening to another Sleep Sound - "Computer Server" (actually the real thing, as we have a computer server in that room and when he hears the noise from the server he always falls asleep - and i'll publish "Computer Server" in coming days).

So give "Sleep Sound - Cricket" a try - and see if it helps your baby get to sleep, and stay asleep. I know it certainly works for my son, so I hope it works for you too.
