Hi there-
If you click on the tabs above BRILLKIDS>LITTLE READER>TESTIMONIALS>OWEN you can read my testimonial for my son Owen (and Lily's next to it too
). I had the very same issue of speech delay with my son and I believe LR has helped it tremendously. I think both of my children are exceptionally bright (don't we all? LOL) but he is simply far slower to speak than my daughter, not sure why? He will actually READ words out loud that he has never attempted to use in everyday speech, and the words he DOES use are almost all words he has been taught to read.
There is no reason that a speech delay will impact his ability to read, and if anything I think it will help it. Best of luck!!
