Sweet how old are your DC?
I bought a musical Advent tree fro QVC years ago. It has a resin tree with hooks (about 15" high) and there's a 'cupboard' with hand painted doors and 24 boxes . Each contains an ornament , I used to put in a couple of chocolate coins .
It still goes up on the 1st. (DD has called dibs on this 'Family Heirloom' when she has DC )
We don't decorate till after DS Birthday .
The winter bedding has already gone on (it has turned cold now) usually that's Dec 1st .
We used to do a Christmas Eve Hamper (PJs , bath bomb, jar of sweets , annual) to get them settled and wind them down.
But now they're teens and don't need winding down (DS needs gee-ing up) they have Dec 1st . They use their PJs all winter , so no Christmas ones , but maybe plaid or polar bear type .
Mine had new robes last year so they're fine .
I'll give him socks, underwear , bath stuff . (Things he needs anyway but they;re not a present )
Ignore the nay sayers . It''s better (IMO) to space things out and not over whelm them.
Maybe if you plan a trip out , give them new hats and gloves .
Take them for tea after . (My DC liked a busy McDonalds in London with their Christmas cups and Matchmakers McFlurries
)
One year we went to WinterWonderland . There was a massive blizzard . London in snow is lovely . We went into Garfunkles for dinner , watched the snow falling .
We had new gloves and snoods .
A lot of the rides were shut but we'd pre-booked (and pre paid) for the wheel, which would've been lovely if we were able to see anything 
My DC still remember it all these years later.
