<p>Gonna toss this out there - married children are considered automatically independent for financial aid purposes. So you actually should not be paying for college once she (if she) gets married. They’d be eligible for a decent amount of financial aid. I would look forward to saving that $$ for the other two and consider yourself off the hook. (Likely she doesn’t know that?) as for the wedding, you’re under no obligation to give anything. But I would, I’d pick an amount somewhere between about $2500 and $5k and that would be it. Never had a wedding in my fam that cost that much either it’s usually a church basement reception and a reasonable priced dress and a small cake plus potluck. ;)</p>
