Kristina on General Hospital...?

I started watching General Hospital a few weeks ago but she is so distracting! Is anyone else distracted by her scenes because of how young she looks? She's suppose to be 17 (and yes I know the actress is 17 in real life, too) but she looks about 12, to me! Am I the only one who can't focus on the show because of that? It annoys me. She looks to young. Especially when she's next to her little sister...
