Hi. Stammering can manifest for various reasons…what we are talking about here is called developmental stammering. Early intervention is always key but essential that your SLT has experience of working with stammering. Treatment can be challenging and if SLT does not have experience, they can do more harm than good. What you do not want to do is focus on fluency, thereby giving the message stammering is not acceptable. Effective communication much more preferable From a parenting perspective, I think very important to be patient when you’re child is speaking. Good eye contact. Pay attention to the message being conveyed rather than focusing on speech per se. What you are looking to do is pay attention to the message rather than focusing on stammered speech. Looking away, finishing sentences, serve to reinforce stammering as BAD in the eyes of your child..this can lead to avoidances of speaking. This creates a vicious circle. Avoidances are (in my experience) and become preferrable to stammering and the perceived negative judgement of others. I would suggest speaking to staff where he will be attending kindergarten. They may or may not have experience of kids attending with stammering. I think important to reinforce this guidance here.. Please note, a lot of kids outgrow their stammering…however, many do not. To maximise your child’s path through childhood and assuming the stammering will be more long lasting than, I would advise you educate yourself around stammering and depending on where you live, access your country’s/states stammering website for info and parenting advice. I can’t state this enough. Pay attention to the message, not the stammering, thereby lessening the perception there is something wrong with stammering. That way, your child will minimise becoming self conscious. So very, very important An analogy I find helpful is to consider stammering as being like an iceberg. The tip above water is what the observer sees, the bulk of what lies underneath is the emotional, cognitive, physiological aspects of stammering which the person who stammers perceived and experiences Stammering does not define a person although many who stammer find this hard to reconcile. Your attitudes now will help to mould a more balanced way in which your child internalises his view of himself I commend you for reaching out. So much wisdom, understanding and compassion here. Best of luck…
