DH and I didn't contribute to our DSs personal expenses last year at college and won't this year. We helped with getting basic dorm supplies and his computer last year, but this year, he really didn't need much. I did pull things from the house to send with him--snacks, paper towels, clorox wipes, etc.
He has a full scholarship for housing, tuition, books and meal plan. Last year, he had a car on campus, this year he does not--he totaled it. DFIL gave ds $300 a semester in a checking account, just to help him with expenses. DS has worked every summer since his junior year of high school and referreed soccer before that and has pretty much always covered his own "going out" money. He also covers his own fraternity fees.
He seems to be managing his money fine and has a few thousand in the bank. Since he doesn't currently have a car, and wants to save a bit more of $$ towards one, he's been looking for campus jobs this year and looks like he'll referee sports through the intramural association. He'll be responsible again for his own spending $$.
I did buy DS a sport coat before school started. I will still buy a few clothing items occassionally and send snacks, but that will be about it.
