Can't tell when your baby has a wet diaper? There's an app for that! We're not kidding.
A new device called "Huggies TweetPee" sends a tweet to parents when their baby has a wet diaper. According to an article in Mashable , TweetPee connects to an iPhone app that alerts you when the device's sensor picks up increased humidity.
The new device has launched in Brazil. You can see how it works in the video below. There only appears to be a Portugese version of the YouTube video available.
