My husband and I have custodial savings accounts for each of our kids and our former foster kids at a credit union that earn 3% per year. The amounts we are saving per kid are much smaller than a lot of folks here, but it seems to be working well so far. It is especially valuable to have the foster girls’ savings in a custodial account under our names, as their bio parents can not get at those funds even if they regain custody of the girls.
We also have custodial Roth IRAs at vanguard for our four oldest kids’ long term savings (up to the amounts they have earned as income and can therefore contribute). The value of oldest’s (13 yo) account has gone down quite a bit since she deposited over $700 of babysitting money in the summer, but I have encouraged her not to keep a close eye on it and not to worry about temporary drops, and she is okay with it.
We do also have 529 accounts for the four older kids, but we only contribute enough to qualify for our state’s tax credit, and focus most of our savings for them into more flexible vehicles.
