DD1 turned 4 the week I went back to work. Yes for us it was partly financial reasons but I'd dithered around for a while having a career crisis and I really just needed to get myself back out there!! In the interim, I'd kept myself busy by volunteering for a local support organisation, and by doing some study - both short courses and a parttime TAFE course. Work turned out to be not-that-mentally-stimulating in the end! LOL

So there are other things you can do, besides work, to keep yourself entertained .
