Re: Just how "many" is many?
I think a lot of things are made for a family of four (two parents, two kids) - cars, hotel rooms, restaurant booths, etc.
Most people I know consider 1 or 2 the norm, with 3 being a bit overwhelming but not too much. Beyond that I think society in general believes four or more is a lot.
However, for me personally, I think six would be the number I would say someone has many children.
