I just realized that iTunes has a huge selection of Parenting podcasts for free! They have some great stuff:

• PregTASTIC's prenatal round table
• Manic Mommies
• FamilyFun TV's activity ideas
• Jumping Monkeys
• MommyCast
• dragonflytv
• Mighty Mommy's Quick & Dirty Tips
• Pedicast
• Storynory
• and more!

Look for them in Podcasts under Kids & Family!
