Hello all!
who can help me? I am looking for an english speaking playgroup in the afternoon tuesdays or wendsdays for my 4 years old son ( close to Bellevue or Kreis 6 or 7 or on the route of the tram 5 or 6)??

try the IPC (international protestant church) or st Andrews anglican church. They both have english-speaking playgroups. The IPC in the summer does a 'rotation' around all the local parks (near Bellevue) and the one that meets in the church hall at St Andrews is called 'Canterbury playgroup'.

There is also an english speaking catholic group at the St Anton's church, but I don't know if they run a playgroup.

I am sure there are plenty of others... not all church based ones...
