KJP,

my 8yo son reacts similarly. so far it's the only time he's gotten in trouble for violence at school. he'd knock the kids down or shove them away from the ants. after he got in trouble, he changed his tactic to picking the kids up and putting them elsewhere. which was not a perfect solution -and we had a talk about that- but distracted the ant-squishers enough that it became less of an issue.

hopefully your son's situation smooths out soon.
