I wish I could. My 4-year-old no longer naps, and I spend most of the afternoon playing with him, chasing him around, feeding him, or worse... scolding him for things he knows he shouldn't do but does anyway. So I take the coffee route, which is not advisable when I'm having a bad day since it only makes me crabbier. I do go to bed early when all these workouts tire me out.
