On this website, you will find many parenting podcasts. It looks like authors of different parenting books are interviewed.
I have not listened to any of them yet. Just discovered the website five minutes ago! But they sure do sound interesting.
Seeing as how, for me, parenting is a work in progress and I never stop learning, this is very exciting and I am looking forward to podcasting out! It's a new verb, one I made up a while back, thanks to Geeky Entrepreneur practically sleeping with his damn mp3 player!
