Work at Home or Kids Franchise?

I've been working from home for about two years now. I've tried a couple of different things during that time but decided that blogging was the way to go. My schedule is my own (which makes it great with four kids).

With the economy hitting the dirt, I am seeing several empty businesses in town. It has me thinking a little bit about what kind of business could be run successfully right now. A specialty shop carrying products you can't find anywhere else but the big city would be a fun business. Any kids franchise would be popular in this area since it is very kid-oriented and when people spend around here, it does tend to be on the kids before themselves.

Then I get to thinking about all the hours that I'd have to devote to an outside business and that my schedule would no longer be my own. I think while my kids are still young, I'll stick to being a work-at-home parent. I want to be home whenever my kids need me right now.
