Childhood experience of poly.

When I was little, there was a quad who lived next door. They were very similar to us, two couples who lived in separate halves of a semi, but were romantically involved and basically lived as a family, with occasional other adult hangers on.
From the children's point of view, it seemed great. There was always an adult around and available to help with whatever they needed, always an adult who was enthusiastic about their current obsession.

I knew others like that, when I was at secondary school, and again, it always seemed good. More adults, more time, more experience.

I'm always attracted to big families, whether it's more children or more adults, maybe? Anyway, i saw the upsides more than the negatives. Now, of course, I see lack of time and a careful balancing act but the benefits still seem to out weigh the negatives.
