I have to disagree with this one. My wife has been a domestic engineer almost since we were married. I wouldn't do her job (actually, I would if she died and I had to).
She does everything around the house. She makes all of the baby food, cooks all of the breakfasts, lunches and dinners and educates our children who -- at their young age -- have three settings: histeric laughter/screaming and yelling.
She doesn't have to commute, but in order to keep the children sleeping through the night, she has a more rigid schedule than I do.
When the kids are older, I'm sure it gets easier, but it's no picnic when you have two under age three.
