I have CTFs for my two ds and have been paying in a monthly amount on top. I'd like however to set up accounts for them that they can't touch until they are at least 21. How do I go about this? I mean, a child account would be in their name so presumably they'd have access to it whenever, and if I put it in my own name it'll be taxed. Whats the best way to save them some money that they won't blow the minute they're i8? Thanks in advance.
