Dear Ms. Aguilar,
Aggressive behavior is not a feature of Attention-Deficit Hyperactivity Disorder. This is not to say that your daughter does not display ADHD, but only to point out that ADHD does not account for her aggressive posture.
Even if your daughter displays ADHD (and she is really too young to be concluding such a diagnosis), her aggression needs to be managed. Generally, a protocol calling for immediate time out in the wake of any aggressive gesture, followed by a gradual re-introduction, whereby she is first required to play by herself for a period of time, then with only one other child, is effective.
If the aggression does not stop in the face of sound behavior management, you should seek evaluation by a pediatric behavioral health cliniciian.
