Yes, I'm afraid they did. Kimberly-Clark Corporation (Huggies) is testing a device in Brazil with a few families that will send out a Tweet when their kids makes peepee in their diaper. Seriously.
TweetPee is apparently a small device that looks like a bird, with a sensor that clips to a diaper. When the diaper is wet, it will alert parents by sending a tweet.CBSNews
The device works with a TweetPee app that lets parents monitor diaper moisture, inventory and keeps count of the average amount of diapers their baby uses.
