The only way to address it is to look into a SLP who is FORMALLY trained to treat dusfluency. Read the posts here. If you do not, your son has a chance of becoming bitter, hopeless and isolated like many here. Early Intervention is your best friend. If you do not have the financial means to acquire the (probably teletherapy) services of a properly trained professional, some of these folks have great free online resources. Im an early childhood professional. If your child is developing normally, he is very aware of his speech differences. Ignoring it will *make everything worse*. You even said he’s very aware there was a problem. He doesn’t want to do speech therapy bc he senses that they *do not have the proper training and are likely making his problems worse*. Most SLPs are trained to treat articulation and swallowing disorders. Does he lisp, drool, or choke on food regularly?
