Melissa, keep in mind that there is a huge difference in being a SAHM and a WAHM.
My wife work from home in her own business. She puts a lot of hours with our media company primarily converting books into different formats (kindle,mobipocket etc) for other authors to sell online. She also is writing her 3rd book to be published next April.
Many people (VT's, sister missionaries, and other people) are under the mistaken impression that because wife is home that she is available at the drop of the hat for teamups, visits,phone calls etc. They do not understand that she is WORKING, not just sitting around.
Big difference. We are blessed that she can work from home to help provide for our family.
