<p>My wife had everything planned out before our first child was born, too. The plan even stayed intact for a couple of weeks after her birth!</p>
<p>Seriously, talking about funding post-secondary education with a prospective parent is like talking about sexual morality with a 10-year-old. Save what you can and deal with your actual children as they grow. You will have plenty of time to think about horizontal equity, and whether there are types of education you won’t fund. The likelihood that your Caltech-eligible child demands to go to truck-driving school is negligible, but it’s all too easy to imagine circumstances in which you would be more than enthusiastic about truck-driving training (assuming there are still trucks and all).</p>
