Now this is how you use talking babies in commercials. Baby milk brand Guigoz and Publicis Conseil team up for campaign 'Let's Talk Baby,' which includes a television spot directed by David Shane and a baby talk app.

The Nestle-owned brand has always been focused on helping new parents understand their little ones and their needs. Its tagline is "Let's Talk Baby,' and the spot takes that message to heart and shows a bunch of adorable babies getting quite opinionated on topics such as a rubber ducky, mom's abusmal stroller-driving skills and a staring family.

The app(check out the demo on the right) is developed by Marcel and available on the iPhone and iPad. It 'translates baby talk' to show you that your little one's "da da da da" is actually a perceptive comment about your shirt choices -- or something else. It lets you film your babies and understand them, and also includes a master database that shows you others' suggested translations.
