I am the 3rd of 4 and was born in a 2 bedroom duplex off Nimitz in Point Loma. When I was 5 we moved to an 1100 Sq Ft mansion where I lived until I left for college.
I was in Africa last month. Families of 6-8 people live in 200-300 sq ft shacks and seem to function exceptionally well (aside from AIDS and Malaria).
Point is, and to pile onto the family thing, size doesn’t matter. I have never heard a kid say they felt responsible for the fact that they live in a small house. I do hear them say they felt responsible for a divorce. The only thing that matters to a kid is a loving, nourishing family.
