What to get a 2 year old and 5 year old who don't actually need anything?

[Starduke]

I have 2 DSes. I have no idea what to get them for Christmas because they seem to have everything they want/need (and we live in a flat and don't have a huge amount of spare space).

The 5 year old loves trains (but has more than enough) and Star wars (but got lots of star wars stuff for his birthday last week).

The 2 year old loves fire engines, cars and motorbikes, but again, has a large collection.

We already have lots of craft stuff, books and DVDs. They love their kitchen, scooters and bikes. They're not huge fans of cuddly toys or dolls.

Any ideas?

If they don't need any things and there is no space for more stuff at home, maybe it's worth to consider tickets to some children attractions? Legoland, Peppapig land, center parcs, Butlins, trip to somewhere? How about all family going somewhere nice for long weekend being Christmas present? And then for the presents sake box up something edible or balloons like pp suggested? That way it will not be a kondo offense committed :)

Do you have a garden? Would something like a nice playhouse work as a big joint present?

Also try to avoid accumulating stuff and in last house we were very short of space.

BOOKS - lots of presents that take up very little space when stacked on the shelf. And do get used. Nice picture books, Lego encyclopaedias that come with one figure. He pores over these for hours, Star Wars books. One year many were "Used - like new". He was none the wiser.

Board games, and then nicer version of stuff he would have got sooner or later anyway - Demon eyes goggles, dive sticks for the pool, pants with super heroes on.

Amazon do a set called 'tap tap art'
It gets played with a lot.

The Melissa and Doug doorbell house would be nice for your 2 year old.

New bedlinen would be lovely and give them an experience (Zara do really nice white sets with cowboys or whatever that would look good in your decluttered home)
