Sounds to me like she's in the "finding how far I can push" phase of her early life. My little one bypassed his terrible twos and instead we have the Terrible Threes...I am sure it's something she will grow out of, they like to push to see how far they can go without a telling off..it's a testing of the fence method, they find a weakness, they exploit...the other thing is, she may be going through an unsecure phase, and by doing naughty things is getting attention, I know it's not good attention, but it's attention none the less...stick with it, sounds like your doing a fine job to me
