One could argue that the very first 'foreign' language taught to Swiss german children is proper High German
There used to be a law once,don't know if it still exists, that it was mandatory to teach ONE of the other official languages of Switzerland from fifth grade onwards,in Swissgerman parts this was usually French, with the option from seventh grade onwards to choose Italian or English.
In the French part of Switzerland this was then often High German that was taught from fifth grade onwards and Italian or English as an optional subject from seventh grade onwards ,and the same principle applies to the Ticino and Grison Alps ( rumantsch)
Nowadays,children often have a better notion of english already in Kindergarten :-) :-),so some of the Cantons have started to teach english BEFORE one of the official swiss languages. This was causing an outcry amongst traditionalists.
I have to admit, that living in a bilingual area,like i do, i would like my kids to learn French first and then English or then both languages at the same time,but that's just my personal opinion.
