If you've ever spent hours pouring over baby name books, get ready to clear your calendar for the next few days. BabyNameWizard.com, the online sibling of the best-selling Baby Name Wizard book, provides visitors with access to three of the author's computer models to help find the perfect name for your lil one. Through Namipedia, you can discover a favorite name's meaning, popularity and origins. The NameVoyager allows you to determine the popularity of names beginning with specific letters over the past 120 years, while the NameMapper tracks the popularity of a specific name in each state over the past 60 years. I've found myself plugging in every name I know, just to see what pops up. Don't say we didn't warn you, this site is addictive!
