Emotional commitment can't be outsourced. You have to be there for their most important moments (recitals, ball games, etc.) You have to spend at least a couple hours every day with your kids, sure. But, for most people, I'd say that if you can outsource cleaning up messes, you should. That way, when you are with your kids, you're energetic and happy rather than overburdened and worn.

Kids with two successful parents who engage with the world on their terms are going to be better off-- they'll have the confidence to expect the world to meet them on their terms, and because they have this, it will-- than if they get somewhat more with-parents time, but their parents are constantly worried about housework and money.
