What should I do

In most states, Hope doesn't need to worry about being smart with the money until she is 18, or any other age as specified in the documents. As her legal guardian, you are in full control of it unless you do something stupid and she or others are aware of it. In that case, they can petition a court to remove you from it. Saving it for her college is a very good idea. Check out the 529 plans or others that provide tax advantages. Also, if you go through a broker or investment house, make sure they charge only a flat reasonable fee per year for managing it, and not a percentage or any other way they churn fees. Having your current bank handle it for you should be free or better.
