Time out! 4 minutes for her age. Find a stool or chair and put her facing the wall. Give her 1 warning, except in cases of hitting and outright disobediance. After the warning say "Time out" physically lead her to the spot and put her in it. After time is up remind her why she was put there and ask for an apology. If she gets out of the spot before you come and get her then start the 4 min all over again but say nothing to her, just put her back. Be prepared for a lot of noise (don't pay attention to it) and escape attempts but eventually she will get the clue that there are consiquences for behavior! I dont put them in their room due to the fact that toys and what not are in there to distract her. I use the hall way where there is nothing to look at.
