I suppose you already have read a lot about stuttering, but if you are looking for information you should check out the [Stuttering Foundation Website. ](http://www.stutteringhelp.org/) They have the basic informations for parents. It's from the 90's but a must watch for parents: [https://www.youtube.com/watch?v=u2_mgt87g1Y](https://www.youtube.com/watch?v=u2_mgt87g1Y) Don't make stuttering a taboo. If your son is visible struggling, he knows that something isn't right. Give him the feeling, that it is ok to stutter. The worst thing about stuttering is holding back because of the fear of stuttering.
