it's funny how different familes have different traditions! we were talking about this on Xmas day as well with all the inlaws and my family
our family always displayed Santa's gift unwrapped and set up...DH's always left the tree completely empty until Xmas morning when Santa would have gotten all the presents out and wrapped them all - they also got the best biggest present at the end...where as with our family we got santa's present first with our stockings before our parents got up!
