Aw, this makes me think of puppies needing to sleep with an alarm clock nearby so it reminds them of their mother's beating heart. Nearly as cute as that image is the My Beating Heart pillow, a plush, cuddly pillow with a heartbeat inside. They say it's not just a sound or a pre-recorded rhythm, apparently, the little computer inside syncs to your heartbeat when you turn it on and relaxes you.
It pretty much sounds like the best nap-maker ever, especially if your spooning partner is out of town. What do you think of the Beating Heart pillow? Freaking you out or mellowing you out?
