I certainly don't copy anything much of my childhood christmas for ds. Would be totally miserable if I did!!
Lead up to Christmas - Mum put the tree up when we weren't about. We had to literally beg her to get xmas cards for us to write to our sch friends to put in the post box at school.
Christmas day - we basically went to midnight mass. Always packed so we would be squished in the side chapel or porch often. Back home we'd put one of dads enormous socks at the end of the bed when we got home. Said sock would be filled by the morning and we were allowed to open those when we woke up.
There were always loads of presents under the tree. However most weren't a surprise as mum was useless at hiding them and I'd always have found (and played) with most well before xmas.
We had to have a full fry up breakfast (am now veggie so wouldn't be doing this) and everyone had to be fully dressed before we could open any presents. Mum like to take a long bath and we'd be climbing up the walls by the time we could open anything.
Presents had to be opened one at a time and in strict order. Said presents then had to be put in an individual pile which had to be taken upstairs and put away directly after present opening was done. I recall one year that one of my presents (an adding machine) was dropped by my sister. By the time it got to the bottom it was smashed. No one said anything I just had to accept it and never got a replacement. Most of my presents seemed to be things my sister had asked for. I got a gurls world doll one time (that my sister had wanted). I had to share it (even on xmas day) and my sister plastered it in the blue eye shadow crayon it came with and it didn't come off 
Mum would go off to cook dinner (it was always later than she said - our oven seemed to play up every xmas). Massive turkey, veg, christmsa pud and all the usual stuff that no-one likes much but you have just because you're meant too...
Rarely had relatives over though sometimes we did have the priest over (always more fun when he came as he told interesting stories about the vegetables and stuff). I remember my gran coming one year with my uncle, she brought us all cindy dolls and he brought me a vase (but it was broken - though I was too polite to say anything on that and dad glued it back together for me).
Dad was always on duty (doctor), so if the phone rang it was possibly a patient and he usually had to go out if it did. Though to be fair most people who called the doctor on xmas day were in need of a doctor and very apologetic for disturbing him on xmas day. But he would sometimes vanish and we'd not see him again for a few hours.
We'd be starving by 2pm (we didn't get much in the way of treats in our stocking, just a satsuma usually so nothing to munch on while waiting) told it wouldn't be long.... Rarely ate before 4pm in reality, often later when oven playing up...
No tv at all allowed, and as presents had all been put away upstairs we would then go upstairs to our rooms to play with any toys we got.
My parents are now abroad at Christmas time so we can do our own thing at least. It's just me and ds and we like it that way.
Before Christmas ds writes his letter to santa, goes to various school fetes and christmas fayres and he gets so excited in the build up! He's counting the days even now.
He gets to have an advent calendar and it's usually got chocolate in it (I never had even a religeous one as a child)
We go shopping together and I look the other way while he chooses my present (it's always a diary and usually he gets it in m&s)
I put the tree up with the lights, but he always helps decorate it (though I have to move some of the decs after otherwise there's be none at the top!)
He makes presents for his grandparents and aunts. Often he decorates the gift bags and makes Christmas cards too (we're making cards tomorrow in fact)
On Christmas eve he puts out a mince pie and carrot. He also leaves his slippers outside his bedroom door (a tradition I was told about by some german friends) and he gets to choose which stockig/sack he'd like to have on his bed.
We read lots of christmas stories on christmas eve before he goes to bed.
He wakes up early, drags his stocking through and climbs into bed with me to open it. We then go back to sleep till it's a more reasonable hour!
In the morning we get up and he then remembers his slippers which are always stuffed full of chocs. Then we go and see the pile of gifts under the tree. (His parenternal grammy sends a big parcel for me and sends money for me to buy more so I am able to make it look impressive with plenty of wrapped up packaged).
He gets to choose one for each of us to open (yes Santa brings me gifts too - last year was a frying pan, a nail polish and some slippers - I wouldn't get things otherwise).
We then have breakfast and he has his special christmas plate and mug which have his name on them and i put out the best cutlery and china that we only use for Christmas. He gets a variety pack of cereal to choose what he wants from (a treat for us).
There's always a hand written note on the table from Santa saying thank you for the mince pie and how much Rudolph enjoyed his carrot.
- Didn't realise how important this was until last year when said letter wasn't on table and he was really upset! It turned up later in the lounge...
We then get dressed and he gets to choose which presents we open and take turns opening. I never insist these go away (though I do get a bit fed up if I'm still tripping over them by the time the tree comes down on 12th night!)
Once presents are opened he gets to play with whatever he likes while I go and do dinner. We have a veggie Christmas. I do all the trimmings and have nut roast which I like. Hhe chooses vegi sausages to have with his as that's what he likes. We have loads of crackers with our lunch (at least three each) and usually get through another box full throughout the day as he loves them so much. We always have profeterols for pudding and a chocolate yule log for later, and I always have appeltiser as a treat to drink (for me, he doesn't like fizzy stuff).
Dinner is always on time and never takes more than an hour to cook all in all. I don't want to be slaving in the kitchen and missing all the fun while I do so...
After lunch we then usually watch a film on tv. In fact we watch loads of xmas tv (we get the radio times and go through marking everything we want to see). Never watch the queen's speech though.
Afternoon is spent relaxing, eating chocs and treats and playing games or watching tv together. I often fall asleep in front of tv, (but only as I've been up half the night)
We stay up as late as we like and no washing up is done until the next day.
Leftover and/or cheese crackers for dinner and we both go to bed tired and happy.
So no, not very much from my childhood I do with ds now (thank goodness!). It's far more special and I love that at 11 he still believes (mostly) and is excited about seeing Santa at the school fete next week and already knows what he is going to ask his for.
