When I first saw the starfield post, I had one kid. I was building her all sorts of cool stuff: brio table, custom childrens book, etc. So naturally, I disbelieved the assertion that my second child would get anything less than my first. Alas, the insight is spot on - for all your good intentions, the second child gets shafted. I think it's just one of those things you have to experience to get it.
