My favourite part of Christmas when I was little was feeling the weight of my stocking on my feet when I woke up very very early in the morning! My parents did this until we were probably about 10 then they left them outside our doors and then when we were older they were left downstairs. I guess because we started going to bed later / not guaranteed to be asleep when they did it!
Dh says his stocking was always left under the tree with some other wrapped gifts from father Christmas.
So what do you do? And at what age?? Because as she is only 3 I wonder if she does wake up and feel the stocking she will literally get up at whatever time that is...So perhaps corner of her room is better or just downstairs.
