From what Ive read, theres a lot of families in the US leaving their homes and living similar to this due to the credit and mortgage crunch.Obviously I dont know the ins and outs of living in the US, but doing that with 4 kids seems a huge undertaking to me,but at least they are staying together as a family.
we lived with our 4 kids like that,it's not that big a deal .and now my oldest is 40 odd we all get on great still and have a good laugh together,never had any of that teenage angst crap either !
