I reared 6, with 2 still at home. It all depends. With a stay at home parent, the curve is shallow. You're likely already got the vehicle you need for transport. Insurance does not go up after 2. So it's just food, clothing, and bunk beds at that point. It's all a matter of life choices. As they get older, if you rear them right, you have built-in baby sitters. Some will point out college. Again, it's a matter of life choices. All mine decided to learn a trade, and so far are very successful at that. The oldest at home is presently apprenticing to be a small aircraft mechanic.
