As a mother of 3, I wanted to tell you that at this age (toddler) it's more about consistency and re-direction than actual "discipline". Don't let anything escalate with her to the point where she feels too upset - try to get her onto something else positive. Also, a large dose of a good sense of humor is essential. Always discipline with love and remember that every decision you make goes into making her personality and shapes who she becomes as an adult.
Have fun!
