we have her apologize (just random hits)and put her in timeout.

My daughter is almost 6 and still does that.... I think it is to get attention. She also pees on things as well, but I think she is more than autistic.

Does anyone in your are use or is there any research going on class by about low level laser therapy? It helps significantly.

Sounds like my daughter. She's usually not angry when she's aggressive she doesn't consider other people's pain or annoyance. We just started on the meds this week so I don't have a recommendation yet. Sometimes I just grab her to keep her away from other people. She's heard it all before but we tell not to hit other people. We started on a behavior program to curb her impulses but if the doctors can't change her maybe only time will.
