I agree with an above comment in regards to speaking slower so he can keep up in conversations. Unless its suspected he is delayed in processing language, I wouldn't worry about this. Speak to him like any other child. For me, the two things that were the most damaging as a child were being told i would grow out of stuttering and having therapists almost force their apparent "cure". For example, I attended a summer program as a kid. Unless we spoke in "the wave"(basically speaking whale for those who may not know but have seen Finding Nemo) and pulled off fluent speech with their chosen technique, they would act as though we hadn't even spoken. They even went as far as to tell my mum not to respond to me unless I spoke fluently. Being told in a roundabout way that stuttering is bad and made me less than other kids was incredibly damaging to my mental health. One thing my mum nailed was advocacy. She advocated hard for me in school to ensure that I would never be put on the spot or forced into public speaking. To be totally honest, im nearly thirty and a mum myself now... and my mum is still amazing enough to handle any calls I need to make. Haha Follow your sons lead. Ask him what he needs from you and the family. Ask him what your doing right and what you need to work on. He will let you know. In terms of friends... they will come. It just might take some time. It took a while for me to make any good friends but once I did, they turned into life long friends. 💕
