Personally I got W a card and small gift (nothing like normal and the card is subdued and not romantic) in my case she suggested bringing s over on boxing day and joining me for a small Christmas drink (he is with W Christmas eve and Christmas day) so this seemed right rather than meeting her at the doorstep with a drink and not giving her anything.
You are in a very different situation but I'd agree with twinmom that I'd definitely get something for ss.
Just my 0.02 though
