luludou - Hmmm, I would guess that The Pajama Elves would work for very young children up to whatever point young ones are still "believing"
It's heavy on pictures, but a really cute idea about the elves magically measuring the children for a special pair of pajamas, how they will be delivered etc. I'm really looking forward to reading the book with DS this year and having a "delivery" of his Christmas PJs!
Have you never seen Meet Me In St Louis? It is SUCH a good movie! I've been showing DS clips of some of the songs on YouTube and I'm hoping he'll watch the full movie with me!
