This will not be a popular post but I never understood the benefit given for more than one kid in college at the same time or by having money adjusted for parents making the choice to have multiple children. I am not talking about low income kids whose EFC would be minimal anyway. Of course I did not plan correctly and had kids about 3 years, 3 months apart , but who ended up 4 grades apart because of the way their birthdays fell. No overlap in college. Bad planning. 
It’s tough because college is so expensive and most people need help. It will be interesting to see what changes end up being implemented.
