Random Aggression

[Guest guest]

Hello! My son is a pretty high-functioning autistic, but he does this

really odd thing. He seems to have this almost compulsive habit of

kicking, biting, punching, throwing rocks at, etc. people for no

apparent reason. He'll be on the playground, playing peacefully, and

out of nowhere he'll just sock the kid standing next to him. Has

anyone else dealt with similar behavior; more importantly, has anyone

had any luck stopping this? Thanks so much!
