Q&A: What Greys Anatomy Episode Has The Little Girl And Her Sleep Walking Dad?

I have all the grey’s anatomy DVD’s season 1-5 (because 6 aint out yet) and my mom and sister was watching the episode with the little girl who thinks she is a super hero. My mom said its the same one who plays the little girl in the one were her dad sleep walks. I say its not. I want to show her. but i dont feel like going through the episodes and finding it. If you know what the episode is called i’d greatly appreaciate it
