I can only speak from experience when I say that please please please don't send ur 2 year old to speech therapy or make him self conscious of his stutter most kids until 8-9 years old won't even tease him for it or anything so he will likely never know or care . My parents did that to me and I believe that the moment I went into speech therapy was the moment I became self conscious of my stutter and have stuttered since because of that. That's just my 2 cents on it. Speech therapy is the one thing I wish I could take back and never ever do.
