My biggest concern was that my son only had about 25 words he was using and they were not consistent. Also, most of his speech was gestures and intelligible babble. Nearing end of his therapy for early intervention after only 4 1/2 months he now has 120 words, stringing together 2-3 word sentences at times and less meltdowns. His vocabulary not including imitation went from 25 words to 120 within only 4 months. His frustration and meltdowns not being able to communicate and needs have decreased significantly and my child now enjoys helping with small tasks.
