Dunno. As an employer, I'd rather take on someone with kids who I thought had a legitimate reason for being out of the workplace than someone with big gaps on their resume. That said, if you were working on eBay sales then that fills in the gap. But honestly, I would think that a lot of people in those positions would have families wouldn't they? I'd probably just tell the truth - and say you were raising a family and working part-time - that shows you can juggle a few things and have the get up and go to do the eBay thing.
