Im sorry you are going through this. This is one of the worst fears a lot of us have. There already has been a lot of great advice given. My dad stuttered growing up and grew out of it. We had some real bad arguments regarding my stutter. Love support and acceptance is what your child needs. I didnt get the acceptance from my dad. Hes a good dad in general, but one of the most hurtful things he said to me was, I am not successful because I stutter. Who wants to hear me stutter? He doesnt understand my self acceptance journey. I wish he can understand my point of view. Looking back his tact with my stuttering just wasnt helpful. I think he always thought I would grow out of it. If he was more supportive and accepting my mindset would be so much better. This is turning into a long post... I am kind of going through the same thing right now.. My almost 4 year old has been diagnosed with apraxia (along with some other issues). He probably speaks at an 18 month old level right now. It's ironic because I was worried about the stuttering of course. I never thought he would have another speech disorder! (Actually my biggest fear now is stuttering on top of the apraxia, but that's a whole other rabbit hole). Obviously with your son and mine there are so many unknowns and who knows how bad it will be. We just have to hope for the best and be there for them. I try having the conversation with him that I know its frustrating that you cant talk. Daddy cant talk either sometimes, but I always want to hear what you have to say. All we can do is be there for them and love and support them.
