Do you put gifts under the tree before Christmas? Or only on Christmas Eve?

Growing up, there were no gifts under the tree until Christmas Eve, after we'd all gone to bed. Maybe the odd gift sent from an aunt or something but all the presents magically arrived over night.

I tend to put gifts under the tree once I've wrapped them, just so I don't have a pile of gifts taking up more space than we've got. DD is only 8.5 months though, so I think once she's older I'll wait until Christmas Eve to put them under the tree.

What do you do?
