Two of my three dc's 'know' and DS (7) suspects, obviously I'm not going to tell him, but I can't help wonder if it won't be easier when he does know. At the moment the presents only appear under the tree once the delivery has been made during the night. We end up having to wait for ages to be sure everyone's asleep etc. Once they all know what really happens do you put the presents around the tree in the days leading up to Christmas day or is that too tempting for them?
