Expecting? Forget lugging around a stack of baby-names books: Finding a name for the new arrival is as easy as shaking an iPhone, thanks to Name That Baby [iTunes Link]!

Created by Shona Killoughery-McKenney, a stay-at-home mom of two kids under five years old, Name That Baby! is a new iPhone application that lists thousands of baby names. Parents-to-be simply choose a gender and a starting letter, then give the iPhone a shake. Name That Baby!, which makes a gentle baby rattle sound when the iPhone is shaken, delivers a scrollable list of baby names, complete with origins and descriptions, in whatever quantity the user chooses. Another shake produces additional names, until the perfect name is found.

The app is currently available in the App Store for $3.99. Next step might be Name That Dog!, Name That Cat! I don’t know, I’m just wild guessing…
