Aww hun, I know what you mean.
I don't currently work from home, but have and plan to after baby arrives. I am an insurance agent, so it's a job you can manage from home, but finding work can be touch.
Selling healthcare like medicare supplemental insurance plans is pretty good, but you have to work really hard at first.
Yes, I work from home as a freelance writer for magazines and websites, but I worked on staff for about a decade before going freelance. And it's essentially running your own business, finding clients and landing assignments, so it's not necessarily steady work. But my husband and I decided I should start freelancing about two years ago specifically so that I would have the option to work from home once we decided to have kids.
