My 2.5 year old daughter has started to push, shove and hit intentionally. She has always been a little aggressive, but she learned and I haven't worried about this in over year. However, about a month ago she was attacked by a 4 year old boy. He pinned her down and started to strangle her in a jumping castle. It took me only 30 seconds to rescue her, but it felt longer and definitely gave us both a shock. She moved on fairly quick, but will bring up the subject randomly and then move on. Now, she is starting to hurt other children for no reason. I can't help but wonder if the "incident" has something to do with her current behavior. She did mention her attacker once when I put her in time out for hurting a child. Your guidance is greatly appreciated.
