I practice in Washington State, not Florida, but I can tell you that the United States Supreme Court has ruled essentially that grandparents have no rights. Your only access to your grandchildren is through their parents. As a grandparent, myself, I can tell you this is very sad. You might try sending birthday cards or messages to the children. Mother has no obligation to give them to kids, however. When your son gave up custody he gave up his rights to give you time with the children. Good luck to you.
