The Business of Being a Mom offers a wealth of information, resources and links. Literally, you could spend hours scanning all they have to offer! They talk about a multitude of topics; legal issues, branding, marketing, inventing, inspiration, mom guilt, confidence and much, much more.
The most impressive page, I thought, was their resources page. Everything from legal help, manufacturing help, to books, to networking sites and business planning and funding, and everything in between. Extremely helpful!
