Trying not to burden my kids with $100k worth of debt the moment they come out of school.
It's a noble gesture on your part.
When my kids first started college my ex and I agreed that we would split their first year between us and the remaining years in thirds.
My daughter followed the plan and graduated with around $25K in student loan debt. She went to a private school.
My son did not follow the plan and Mommy and Daddy cut off the checkbook when he was asked NOT to return for the sophomore year. He went on to get his 2 and 4 year degrees, his MBA and is talking about going for his DBA. He left grad school with about $73K in student loan debt.
I borrowed from my 401k to finance my portion of the expenses.
