I totally paid for my daughter's education to the grad degree level. Bought her her first and second car, taken her on numerous luxury vacations, gifted her enough stock for a house down payment ( subsequently has turned out to not be enough. So will likely have to give her more). Bought her and her new husband memberships in a very nice club. Paid for her fairly large wedding. She has never asked for anything. Very serious, careful, sensitive, hard working, intelligent young woman. I am proud of her.
If I were to rank the expenditures in order of "importance", I would certainly start with education. Second would probably be assistance with a house down payment. Obviously these types of assistance are dependant on your ability to pay them.
Obviously I have been very generous. Probably out of guilt for leaving her mother when she was 8 years old. Has not caused her to act entitled, dependant, or work less hard. Every kid is different as is your relationship with them. I believe I have a wonderful relationship with her and want to help her accordingly. Only heir so she is going to get most of it eventually anyway.
