If you are setting aside funds for your child's/ children's college, how much are you looking to have in the fund when the time comes?

What are the hopes for the fund? Tuition/ Books/ Room & Board/ work/study abroad/ Grad school/ Car/transportation/ Private/ Public

As DH insists on a second, I wonder if we really are planning for enough. Curious to see what others are doing. I'm sure eventually we will sit down with a FP to discuss. We have two very different experiences cost-wise for college.
