Kitkats: Harmless choco wafers? Or massive destruction baby energy pills?

Trying new stuff for my two year old sister is like waiting for a worldwide food critic to rate every meticulous amount of food I put in my mouth. Every time I make waffles in the morning...
"Anna?"

"Yes, Nat?"

"I wanna have some!"

When it comes to having burgers, she basically goes all spazz attack on me and practically jumps up on the chair (which is about a foot or two higher than she is).

And the worst part of it all is that when she gets a hold of all that, she goes all crazy. She starts screaming like a parrot on steroids. And she starts babbling and talkiing gibberish, like, "Annnnnnnnnnn....bur...flipy... HE WANTS A.... AYNNNNNNNNNNNNNNNNAAA!!!!!!" Did that make any sense? Well, it shouldn't, 'cause that's how she is. When she's around people she doesn't know, she still thinks it's okay to go completely balistic.

So, yeah. But I think i can deal okay... until it comes to Kitkat bars. That's right, those delicious choco wafer morsals that can make anyone drool. However, when it comes to a crazy meglomaniac of a toddler, those "take a break's" become "take a thousand steroids." 

So, within five seconds of sight of those tasty candies, she totally, irrevokably, loses. It.
