As others have said, seeing a speech pathologist for a formal evaluation is the best way to go. Lots of factors can come into play when it comes to whether a stutter in a young child is a cause for concern, such as the age of stuttering onset, how long your kiddo has been stuttering, and family history of stuttering. An SLP can determine if services are needed, or make the call about using a “wait and see” approach. For the time being, it is OKAY to talk about your child’s stuttering if he brings it up that he “can’t talk right.” You could respond by saying “sometimes talking can be a little hard, but I like the way you talk and I love hearing what you have to say!” You can also lower the demands that are placed on your little one when he speaks and basically create an environment where he feels safe and respected when talking. As mentioned before, talking slowly yourself helps model an even pace and also helps your child feel that there is plenty of time for him to say what he wants to say. Giving your child your full attention when he’s talking also helps remind him that what he says matters and that you enjoy hearing him speak. Those are just a few tips, but your SLP can provide much more information and guidance, as well as take into account the individual needs of your family and kiddo. I wish all the best for you and your child!
