Hi AwesomeWellies, I'm not much help on German carols I'm afraid as virtually all our Christmas CDs are English. I think we might have one German CD that we got as a freebie, but we've never actually bought any. Must confess I'm not very up on German carols. 
whateverfloatsyourboat - I've been in Austria for 7 years now; we live just outside Vienna. How old are your DC?
Canella - sounds like you had a lovely time with your friend and introduced her to all the key Christmas experiences! It made me think of when we introduced my mum to Glühwein; she gulped it down like she would a cup of tea, not realising how much alcohol was in it, and quickly had to have some apple strudel to soak up the alcohol!
ad - love your Christmas name! Our house is a tip at the moment too, largely thanks to me working every spare minute of the day. However, it somehow manages to be almost as bad even when I'm not working. One day I will find time to declutter.
bananas - I manage to get away without baking quite easily! DH will occasionally make Christmas biscuits with the DC, but cheats by buying that ready-made pastry dough (which seems to go down well enough). The only place I've ever had to bake was in the USA, when the playgroup I went to held a cookie exchange - fortunately the Austrians don't seem to be into that kind of thing! (Although I did enjoy it at the time.)
DH took DS to the Lungenfacharzt this afternoon, but we aren't much further along in finding out what's wrong with him. We'll get the results of his blood tests in two weeks and she has also referred him to the HNO-Arzt for a check-up. In the meantime, he has an inhaler that he has to use every day until the next appointment. DD2 has her appointment wrt the Herzgeräusche at the Kinderarzt tomorrow; she's also been complaining of stomach aches fairly often recently, so we'll have to get that checked out too.
It looks like I'm the only one who finds lukewarm octopus unappetising, then.
I am getting fed up of Christmas recipes now - although I've just translated one for glögg which is making me wish for a mug of Glühwein!
