P.
She is probably old enough to start denying her some of her favorite toys or tv programs as a result of not listening. When mine were her age I would tell them that if they did not follow directions or were acting inappropriately I would take away their (insert favorite toy/program) for the rest of the mprning/afternoon or the whole day if the action was severe. It is also important to reward her for following directions or acting appropriately. The reward can be as simple as clapping, praising, and hugs work great. I have found that nothing is easy at that age so it will take some patience and consistency. I still battle these very same issues with my 2 and 4 year olds with a dash of attitude ;o) Good luck!
