Who brings them to school? Takes them to the doctor's? Pack lunches, make dinners? Bathes? Etc.
I work full time and my wife part time so she does more than I do but I still help. I get up early and make my daughter's breakfast and pack her lunch and my wife drives her to school and back. Whenever I have a day off I drive my daughter to school to give my wife a break. My wife almost always takes our daughter to the doctor but when I'm not working I go too. My wife and I do about the same amount of cooking. My wife does all of the laundry but I do some of the hanging, folding, and putting away. I do most of the yard work and house maintenance.
I take the brunt of the work but he is the one who's out roofing for week on end out of town.
