No. I never saved/am not saving for the university years. At 18 adults make adult choices, and should be prepared to pay for them.
That's not to say I won't help them!
I have 3 adult DC.
DS1 is nearly 30. He spent 4 years at university, and has now paid off his student loan. He was sensible with his money, so didn't get into too much debt. He worked during holidays,and was fortunate to be sponsored by his future employer for his final year. We helped with the cost of books, train tickets to and from university, some money towards food when needed, and free board during the holidays. He was very fortunate that he unlike most of his friends only paid rent at university for the weeks he was there. So many student have to pay a full years rent once they are out of halls.
DD is still paying off her loans, but she had more holidays, and a very full social life whilst at university. She did however work during her holidays. She was a bit , when I pointed out that DH and I would not be funding the trip around Europe, or the gap year that some friends parents seemed happy to fund. But she got over it. She will enjoy these things much more if she pays for them herself.
DS2 did an apprenticeship. No loans, no debt, bought his car for cash, has lived in his OWN home for over a year.....Very sensible young man.
Still got it all to go through again with 3 teenagers. I will help them to go to university, but will not fund it. It is not simply a continuation of schooldays with mum and dad footing the bill.
I may have felt differently if I had gone to university myself. I am now an older parent. The majority of my generation left school at 15, or if they were lucky at 16 with O levels. At that age we were adults.
