My 28yo son is living at home. He earns £45k and pays £350.00 housekeeping per month. My husband and I struggle with household bills coming in left right and centre but want to help son save for house deposit. We cant afford a holiday but son is going away for 2 weeks to Europe on mega holiday with girlfriends family (again!) which he has paid for. My question is should I charge a full months housekeeping even though he is away for half the month or just charge for the weeks he is here? He will bring home all his washing for me to do too.
