Speech Therapy Needed?

It is amazing how two mothers looking at the same child can come to totally different conclusions. After several months of speech therapy, my child is attempting words like a pro. Overheard by one mother, he was praised for really responding to therapy. Another mom noted after the first left, "you know, he did it on his own, the therapy isn't anything but a scam". Hmm. I think it is a combination of both, and in either case, he is not up to developmental norms. So, we continue therapy and I am quite confident that some of it is due to a wonderful therapist, and some of it due to his being a smart little boy who needed some extra time.
