Our credit union allows kids to have savings accounts with a modest ($25) minimum balance, and pays them a (very) marginally higher interest rate than it pays grown-ups, plus various promotions/literature to encourage them to save. Is something like that an option? We set up 2 account for DS (both at the credit union), a savings account that is for "his" money e.g. stuff people give him as gifts to spend on things he wants, saved allowance, and a money market account that is for larger amounts of money that (e.g.) people give him that isn't for him to spend directly but for us to use on his behalf. Obviously the fact that we have this range of gifts on behalf of DS marks us as pretty privileged, so there's that.
