The luxembourgish audiophonological institute has finally managed to produce a leaflet for stuttering kids. It took them about 1.5 years for four pages, even though I have given them a corrected version of their old leaflet.
It's in German and French, and I have to say that at least I cannot disagree with what they wrote, only the infantile font they used. They used to write that stuttering can be due to psychological stress from their social environment but not anymore. Progress has arrived in Luxembourg. See here.
(Thanks to Lukas for telling me about stuff happening in my own country!)
