I recently returned to full time work after 4 years of staying at home. I think sometimes it depends on your industry, but I actually got a lot of positive feedback and got hired pretty quickly. I was honest about staying at home with my children. I did take a few contracts and worked at a seasonal job every spring and fall -just for a few weeks and NOT in my field -but for the most part I was at home. Contrary to a lot that we hear, I think more and more businesses and companies realize that often, mothers or fathers choose to stay with the kids for a few years. Talk up how you've been multi-tasking, organizing, delegating and managing a household and joke a bit about how you never thought it could possibly be that hard -but it is! Let them know that you are making the decision to return to full-time work because it's TIME for you. I got the feeling that was a big selling point of mine -that I had been home, but I felt it was time because I need it, not because we were in financial straits or had to go back to work. It doesn't matter why you're REALLY going back -play it off as that regardless.
Definitely use Monster.com -this is where the majority of my interviews and offers came from. Also, see if Indeed.com serves the Portland area -I got MANY great leads from there. Careerbuilder.com also worked for me. Be willing to go in under a contracting company if it has the possibility of turning into a permanent position. Also, if you're not finding what you want -be willing to work as a contractor for 3,6, or 12 months. Often that will lead to permanent employment,and it does give you good, recent experience.
