Best way to gift kids with money?

This is a question for a CPA with the amounts you are considering

Why would you give a teenager a quarter of a million dollars? I’m not too keen with financial jargon but what I do know is, that money would be better spent after she graduates. Why give her access to $250,000 now when outside of books, she would be paying for frivolous things? I know speaking for myself, I would much rather have $250,000 when I’m 23 looking to get a nice apartment or car than have it now when I would be spending it on unnecessary things. Or even better, give her $15,000 a year for the next 15 years.
