So I know there's a shushing device out there that costs money but I'm cheap, so on a whim I downloaded an app for it instead.
I decided to try it out the other day because I've noticed that the shushing noise actually does work (the majority of the time) when I'm trying to get Charlie to sleep.
We were in the living room, the dogs were playing and being noisy. I wrapped up Charlie, sat in the glider, turned off the tv and turned on the app.
The dogs.... fell asleep... lol
Charlie did too after a while but I'm not sure if it was the shushing noise or the gliding or just being tired. Almost put me to sleep, too!
