TweetPee is a device
that has the shape of a bird(very much like the Twitter logo) with a sensor that stick to the diaper. Whenever your bay diaper is wet, with the TweetPee app, it sends a tweet that your baby has a wet diaper.
Four Brazilian parents have been tested and it works. Huggies, the maker, said they develop the device to help parents monitor the amount of diapers their baby uses.
