A friend of mine shared a really great site through GoogleReader. It's a great site for those of us with barren uterii (no kids) and designed especially for aunts, great aunts, godmothers, etc..
It's Savvy Auntie! That's me - I'm an aunt. The site has just recently gotten up and running and is in its beta version. Categories include "Dear Savvy Auntie" (advice column), "Going Out" (tips for taking out the nieces & nephews), "Special Needs Aunt's Getting Started Guide" (for aunts with extra-special kids in their lives), and more!
No, it's not a mommy site, but it's a site I can use for now. Until I get pg/jump the broom/kill the rabbit/get to use the mommy site of course!
