Have you checked out The Afterbirth yet? It's my sometimes daily blog where I publish little snippets of Motherhood as I see and experience them. And while I want to keep this little place to share my thoughts to well, myself, I'm hoping other writer mamas out there are interested in sharing their own thoughts. Call it ego or an OCD need to plan for every eventuality, but I already have a blog name and URL purchased and ready to go for my own vision of a spin-off of The Afterbirth. I'm not doing anything with it until I know that I'd have a constant and ready supply of writing to post from contributors, though.
So until then, it's just an idea. The rest is up to you.
