For the most part there are very few quality podcasts that have the parents of gamers in mind.  The web site WhatTheyPlay was created to provide parents with a helpful resource to find out about video games.  The site's creator, John Davidson, has now started a podcast where he talks about the games he's playing with his two young boys.  The podcast also covers some listener questions and about games the listeners are playing with their kids.  This is a very nice compliment to the site and it's a fairly short podcast so you don't have to dedicate much time to listening.  I highly recommend check this site out as they are on iTunes and you can subscribe to the podcast's RSS feed in the Zune software.
