Sorry, it was Adora who said he should apologise. The thing is, I don't believe in negotiating with children, but DH has harder still expectations than I do.
The stupid thing is, that DH doesn't really care if DS does his homework or not, as long as DS just says he isn't going to do it, rather than saying it is done, when it isn't.
I asked the school what further sanctions they have if detentions aren't working, and they said they didn't want to escalate it at this stage, just for me to be aware if the position, so I know what is going on. Talking to a friend, at her son's school, she receives a text if her son gets a detention for filing to turn in homework. I'm going to suggest this might be a good policy for our school to adopt.
I am going to ask to be made aware each time he doesn't turn in homework.
I can check his "show my homework" where most homework is posted online, but not all if it. I don't think DS realises this is punishment for me too.
