Thanks Teeki, we've always done similar, and normally it works but at the moment they have thrown that to the wind I suppose. I currently have yesterday's presents packed up thanks to their behaviour, let's just say respecting ones toys (and toys that they have begged for for the last year, and ones that Santa brought) doesn't exist. Respect for me and dh has gone out the window too. Probably not the best combination at the moment either.
