I paid for all expenses for my kids while they were in college. It included books, computer, travel home, tuition, etc. I also gave them monthly allowance, but in order to get the allowance they had to work 10 hrs a week. They had to maintain minimum 3.0 GPA. To stay in their sorority they had to have 3.5 GPA. The reason I wanted them to have a job while in school was to have work experience on their resume. They were also required to work every summer and it had to be paid work.
Some people may think my kids had it easier than others because they had everything paid for and plus some, therefore they may feel entitled and would expect to be supported by me after graduation. They are both out of college ad are working at 80+ hrs a week jobs, except the older one makes an IB salary and the younger one works for less than 60K a year in NYC. Both of my kids live within their means. D2 goes to a lot of free events, and D1 splurges a lot on her younger sister (paying for meals, and nice handbags).
