I wasn't sure whether to post this in "Parenting" or "Investing", but I recently found out that my credit union offer's "early investor savings accounts" (that is, for anyone under 17) at 6% interest up to the first $500, then some negligible rate above that. So I'm going to open accounts for my kids and put in the $500. It's kind of small potatoes in terms of the overall stash, but I can't think of a safer way to get interest at that rate, and when my kids are older it might be a way to teach them about savings. The downside is that it's not a great lesson in compounding interest since the interest won't grow at the same rate, but maybe I can convince them to transfer their earnings above $500 into a Vanguard Fund...
