On Juggling Parenting, Work and Play

I keep wanting to put the comma in before the and.  I wanted On Juggling Parenting, Work, and Play.  It feels right, and I checked Grammar Girl, and she doesn't think it's WRONG...so why does Microsoft? 

I am trying to figure out a schedule.  I work 40+ hours per week at a "professional" type job.  I have three children, and a horse.  I am trying to figure out how to balance all this so that the house gets and then stays clean, the kids all get what they need, support wise, for homework, and I can ride.

So far, my best solution is to add 7 hours to the standard day.  I need them for sleep.  I bagged the housework, a clean house is vastly overrated anyway, and I still can't get it all together.  This is ridiculous.

Clearly this must be possible, I know other parents work full-time and still have time to be in training.
