The stats I have seen suggest that full time moms do 60 hours of women's work per week. Working moms still do 40. To make up for the loss of 20 hours of women's work, men began doing an extra 10 minutes per day, or 1 hour and 10 minutes per week.

Those stats are not current. Given the reactions I got from working women at a Fortune 500 company over the detail that my sons took over the cooking and cleaning, I have zero reason to believe we are anywhere near achieving parity.
