OP, my concern is that your younger child might have selected private college based on the assumption that it would not affect financial arrangements for grad school. You seem to be changing the rules of the game in mid stream. You should be ready to explain that to your younger child.
I think this is a good point ... You may get yourself into a vicious cycle here of "fair." What if youngest chooses a cheap grad school? Will you contribute?
I think you stick with what you said for college/grad school, but keep an open mind about helping the oldest out if she gets into financial difficulty or could use some help other than with tuition.
