How much can I get away with?

BG's starting to display a little rebellious streak here and there. She's got these moments when you can tell she knows what she's doing is wrong but is doing it anyways.

The other day, I changed her diaper, and left the package of wipes just sitting on the floor as I went to the bathroom to rise off her diaper and put it in her diaper pail. When I got back to her room, I saw her with a huge wad of wipes next to her, another wad in one hand, as her other hand was pulling yet more out of the box.

I yelled out, and she jumped, looked up at me, and then with a wry little smile, never taking her eyes off of me, she continues to pull more and more wipes out until I come over and stop her.

Little bugger totally knew what she was doing was wrong.

Then this morning, BG woke up at 6:30 as usual, but as usual, Jeff and I didn't end up getting to bed till around 1am, (stupid tv and computer distractions!!) and so we were both pretty exhausted. Jeff took her to her room, changed her diaper, then laid down on the ground and let her crawl around her room pulling toys out of her toy box, playing by herself. When he woke up, he saw a few wipes strewn about the room, and she was sitting there playing with a few more that were in her hands.

He looks over to the wipes container and sure enough the lid was closed, sitting exactly were he had left it after he diaper change. It was as if she had "covered her own tracks" so that he wouldn't know that she had gotten into the wipes again.

And I figure, it's probably too soon to begin "punishing" her for doing things I tell her not to right? There have been many times she goes for the wipes, or pulls my glasses off my face, or reaches for something on a high shelf that she shouldn't be getting to. I tell her no, and I pull her away from whatever it is that she's trying to do, but I'm afraid that her first words are going to end up being no!

If she's anything like me, she's going to push and push to see how far she can get. So when do I start putting down my foot? When do I start punishing her for going against something that I say. You could argue that she doesn't quite understand what she's doing, or what i'm saying, or what I mean, but when she looks defiantly into my eyes, with a sly smile on her face, as she continues to do something I specifically told her not to, I have a hard time believing that she doesn't understand me.
