This Sleep Sound is a 56 minute recording of a car trip.

As nearly every parent knows, a crying baby will always fall asleep as soon as you take them for a drive in the car – and my son Alexander is no exception. As soon as we're in the car, he's off to sleepy-sleepy land.

With that concept in mind, I set up my recording equipment in my car during a car trip from Parramatta (in the western suburbs of Sydney, Australia) to the Blue Mountains (where we live) – which is about two hours west of Sydney CBD, and home to many world famous tourist locations such as the Three Sisters rock formation, the Megalong Valley, and the SkyWay cable car.

If you listen carefully to the background at around the 52 minute point, as I was driving through the mountains village of Wentworth Falls, you'll hear the screeches from a flock of Cockatoos flying over my car – it's pretty quiet, so you'll have to listen hard.

I've played this recording to my son Alexander many times, and it seems to work as good as a real car trip – even with the very quiet Cockatoos near the end of the recording.

So give "Sleep Sound – Car Trip" 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.
