After some soul searching and talking to some friends, I have decided to apply for the job at my old office. My logic is that if I don't get it, I stay at home and take care of the kids. If I get it and get to work from home, bonus. My goal is to work from home as much as possible and still take care of the kids (and even watch a friends' daughter after school). If they can/will not accommodate that, then nothing ventured, nothing gained. :)
Now to work on a resume (luckily I have a friend helping me) and work on a schedule that, hopefully, everyone can work around. I'm not 100% sure what to do in the summer, but we'll cross that bridge later.
