We have got our own traditions since having dd (she will be 3 at the end of jan). we put up decorations when she is a sleep so we can see her excitement when she see them for the first time.
She has a christmas sack on her bed which we open on our bed.
Then i go down stairs to put on kettle (very Important) turn on tree lights get video camera, then dh brings her down and the look on her face when she see all the pressents under tree (put under when she is a sleep). She opens as many pressents as she wants at the speed she wants.
We have a light breakfast, then Dinner at about 2pm my mum comes for lunch and then my sister and her dh come late afternoon early evening for tea cheese and crackers and cake if wanted.
The most important thing about the day is that it is done a relax pace.
Then we have to go to mil on boxing day where we then have to have eat christmas diner again at 2pm with veg that is put on to cook at the same time as the roast potatoes. Forced to eat vast amount of food.
They have a very tidy santa who puts all the grandchildrens pressents in nice neat piles for each child.
Then at 5pm she will be making sandwiches etc in case your are hungry. Then get enoyed that no one wants to eat.
I will say we will not be staying late or staying over after last year.
