My wife the Psychologist; and I didn't even know it...

I know I am British but I found this article about American families.

If the typical stay-at-home mother in the United States were paid for her work as housekeeper, cook and psychologist among other roles, she would would earn $138,095 a year, according to research released Wednesday.

This reflected a 3 percent raise from last year's $134,121, according to Salary.com Inc , Waltham, Massachusetts-based compensation experts. The 10 jobs listed as comprising a mother's work were housekeeper, cook, day care center teacher, laundry machine operator, van driver, facilities manager, janitor, computer operator, chief executive officer and psychologist, it said.

Respect, I still wouldn't swap with the wife to look after the children on my own!
