I'd suggest a Fastmail.fm account instead. Their TOS says: This Service is provided to individuals who are at least 18 years old or minors who have parental permission to open and maintain an account. I think I read somewhere that they consider a charge on a parent's credit card to be explicit parental consent. Makes sense to me. Also, since you are paying them a little money, they offer actual technical support, unlike Google. They also have family accounts, where you can have one person take care of billing and administration of several accounts. That's what I use for my whole family, including my parents.
