We have the Graco white noise machine which we keep in our bedroom for at night. We also have the Sleep Sheep attached to the crib in the nursery and a Sleep Sheep On The Go. I think they all do a pretty good job of keeping her sleeping once she is asleep. BUT, I HATE how the Sleep Sheep turns off!
I guess I had the Sleep Sheep on the shorter timer today and as soon as it went off she was awake! Argh! I'm almost tempted to buy another plug-in white noise for a 2nd room so I don't always have to move them back and forth.

Anyone else's LO wake up when the Sheep shuts off?
