So Leigh and I are fairly obsessed with the topic of baby names lately. With Boy #4 on the way, we have struggled to pick a name (I will never tell). We have used up most family names, and I have the added difficulty of associating certain names with patients. This is neither a good or a bad thing, it just means that I already know seven Jacobs and five Ethans. Way back in the dark ages when Walt was born, our favorite book was Beyond Jennifer and Jason, Madison and Montana. It served us well at the time, but everything is online these days. The same authors of "Beyond Jennifer and Jason" now have their own website, Nameberry. This is still our favorite site, as it provides advice, opinion, and flavor in addition to the usual lists of names. You may also find the following sites useful. I would love to hear feedback about your favorite baby name websites.
Baby Name Genie - fun but limited site that makes suggestions for you.
Baby Name Wizard - lots of historical data and baby name resources.
Baby Center's Baby Names Finder - popular baby website has lots of cool tools to help pick a name.
