The only thing that can be done (and probably all that needs to be done) without going to court is for your parents to give your grandma a power of attorney authorizing her to do anything the parent can do. In Colorado it is call a Delegation of Parental Authority. This document simply gives your grandma the authority to do things such as consent to medical treatment, deal with school authorities, etc. instead of requiring the parent. There should not be any need for anything else because your parents can't simply "give up" their rights and obligations as your parents except in a court proceeding to appoint someone as a legal guardian.
