It sounds like you're already making some sort of headway with her, Sena. I believe that if you're dedicated to teaching her, she will learn. Think of it as practice for your future munchkin's terrible twos, and teen years. XD
I hate to say it (mostly because people think I'm nuts) but in my experience, raising a younger child is like raising a dog. Repetition! (Only the dog was easier to teach to stay out of things she's not supposed to get into)
My dog only averts her gaze when I'm eating. I don't like being stared at when I'm trying to eat something... if she keeps her eyes averted, I'll "accidentally" drop something after I'm done, like a small piece of chicken or beef.
