3pigs the Christmas Eve Hamper can be done at any age 
By Christmas, mine will be 15 and 12.6 . Their Christmas presents get smaller and more expensive so their present pile is tiny.
The CEH - a nice box (TKMaxx/Homesense/ last year I bought plastic weave type boxes , decorated with ribbon and cellophane)
PJs (Primark fleece or flannel. DD likes Christmas ones, DS has plaid)
Dressing gown
Annual (always on BOGOF in Sainsburys or WHSmith)
Jar of sweets
Mug
Small pack biscuits
Sachet hot chocolate
Bath Bomb (Tied to the outside if it's Lush, they make everything smell )
We do a traditional family shopping trip. Either an evening or a Sunday (once all the Christmas shopping has been done except food) We have a £2 jar from NYD so we cash it up, usually £200-£240 shared between 4.
The DC each choose a new decoration
We used to take them for a walk to feed the geese or reindeer. Then when they were older, the park, now the cinema.
The Hamper appears after the trip out.
Some people say "What;s the point of CEH, they get enough presents" but they are a (IMO) to signal the start of Christmas, to calm them down. Bath, PJs, read, DVD, hot chocolate then sleep.
It's lovely and most of the CEH things are things they need and use anyway.
