All of mine are currently in the storage unit along with our decorations etc, so I can't be exact. They'll come home roughly 1st December, even if I know DD won't read them anymore (she will probably watch some of the seasonal DVDs though). But we've had a selection of Christmas and winter books that have been well loved over the years. Some have moved on within the family as DD has gotten older, but some we cannot bear to part with.
Small, individual stories books:
I've got a number of the Mr Men seasonal books - there are about 5 or 6 in the range.
We also have a Thomas the Tank Christmas book.
We have a French book called "24 petits souris avant le Noel" - which is the daily adventures of some of the family of Granma, Mum and Dad mouse and their 21 children as they prep for Christmas, ending on 24th December. Simple enough French to read and then translate. If either parent has a smattering of another language and wants to start introducing it to the DCs, getting a kids Christmas tale in that language, reading it and then translating it can be fun. (Although, DD ended up picking german at school....
).
Bigger books:
I had an anthology of Christmas poems, short stories and individual chapters from longer books which is also nice to pick a page at random from.
A pop-up version of A Christmas Carol.
Picture books:
There was a book from the company that have a duck on each page (Usborne?) about Floss, a sheepdog who rescued a flock in a snowstorm.
There was also one about a kitten growing up in winter on a farm and meeting santa, which had bells on a ribbon to tie it closed.
If you go into a good bookshop from now onwards (and particularly around mid-Oct to late Nov), there is likely to be a range of different ones to choose from, from the larger picture books, to the smaller ones, and also the longer ones - full novels or anthologies; and aimed at different age groups too. If you can find someone in that bookshop who deals with the kids section, they are often terribly helpful and only too delighted to try and help you.
I also have a few stories I had printed off the internet over the years and put a cover on, Santaupdate.com has a few that are printable and have nice pictures, but there are others. (And those websites often have colouring sheets or seasonal activity sheets to print off as well to entertain smallies in Dec - mostly free but some are payable).
