Not a parent, but I’d assume you’re under no moral or legal obligation to give them any consideration at all. Your child misbehaves, the teachers are handling the behaviour as best they can, and you are informed and abreast of all the developments, and working with your son to try to minimise these behaviours.
You CAN meet with the other parents and offer an apology and so on, but you could just be opening yourself up for getting an earful over something neither you nor your son can really control. Or, the other parents could be really understanding and considerate. It’s a mixed bag.
