One quote idea for a parent-to-child yearbook dedication comes from Anne Frank: “Parents can only give good advice or put them on the right paths, but the final forming of a person's character lies in their own hands.” Another quote idea comes from Mitch Albom's book "The Five People You Meet in Heaven," stating that “Parents rarely let go of their children, so children let go of them."
Anne Frank's statement works for a yearbook dedication from parent to child because it highlights the parent's work in guiding and shaping the child, while also indicating to the child that, ultimately, his character disposition depends on his own deeds and choices. The quote encourages a child to draw on advice from his upbringing but also take responsibility for his own actions.
Mitch Albom's quote from "The Five People You Meet in Heaven" goes on to say that children "move on. They move away. The moments that used to define them - a mother's approval, a father's nod - are covered by moments of their own accomplishments." In other words, Albom suggests that, as children grow up, they start looking more to the outside world for approval than from their parents, and this process helps them grow into adults.
