My Year 7 DS forgot his RE homework today. He rang me at breaktime and asked me if I could drop it at school reception for him, so I did. His RE teacher had sent a note home before half term saying that too many children were not doing their homework so after half term, detentions would be issued to anyone who did not bring it in (DS has always done and handed in the homework before but would, of course, have been included in this new punishment today)
DH thinks I should have left him to face the consequences of leaving his homework at home so that he takes more care in future.
At the start of YR7, I was 'carrying' him with regards to organising himself with homework, books, sports kits etc but I've been able to step back, he's got to grips with it and he pretty much organises himself now - so to be honest, I don't want him to get into trouble 
What would you have done?
