I put myself through uni, I can get why parents want to help their children, but lets face it they dont have.
A lot of children are having to support themselves through uni, with no parental help, because parents cant afford it.
There are always options such as Camp America, etc, for the holidays (which are fantastic opportunities in their own right and which I will be encouraging my DC to aim for).
CSA btw can over ride any financial agreements made now, so long as there is a certain time scale for them to run.
My agreement with eldests dad (very losely), is if DC lives at home for uni, he is going to help me out and give most to DC, but if DC goes away to uni, he is going to give money direct to DC.
However I very much doubt his money will be as much as it is while eldest is in school.
