You'll find you get very resourceful with a baby in Switzerland. Although, having also travelled in France, Spain and Italy with my son I can say Switzerland comes off pretty good for baby facilities.
In Italy they looked at me as if I'd asked "where can I disembowel my pet donkey?" when I asked "where are the changing facilities?"
Not many places have nappy changing areas but I have a good foldable changing mat which can be folded out in loads of places. I've also changed him flat in his pram so that's always an option, although perhaps not in a crowded restaurant if it's a real humdinger of a nappy!
Breastfeeding is positively encouraged here and I never received any negative feedback from feeding my son whilst out and about (I think most people were happy he'd just shut up wailing

).
EDIT: Parenting rooms - now that's a snappy new bit of terminology I've never heard before.
