I've been an artist since I was a kid, and I was like your dd with my obsessive art making followed by long droughts. I've been spoiled that I could always "render" extremely well - and maybe that's made me lazy. But despite long breaks in art-making, art has never left me.

Now I realize that I enjoy a creative challenge to keep my passion, sometimes it's tradional visual arts like pastel-work, but often it's less conventional like jewelry design, creative writing, cake decorating, or cooking. I'm fickle I guess. While preparing for a watercolor show, all I could think about was learning the art of portrait photography. And manual photography led me to advanced photoshop which led me to digital painting (and who knows what next?).

Often art and creativity brews in our minds for a long time before it manifests itself concretely. If your dd is happy and using her creativity in other ways, I wouldn't push. If she hes sn artist's heart, she'll home back.
