Please recommend your speech therapist. I have a 3.5 and 1.5 year old, both who are currently in therpay. I am not crazy about the speech therapy provided at our current clinic. If you love your SLP, please recommend. We are in Glenview, but are willing to travel anywhere in the northern Chicago suburbs.
i am doing all the ST and OT through our ABA program. And thanks to it, he is starting to say words with meaning. I started PT, ST and OT very early, he was not even a year old, but ST was failing... the therapist weren't unable to get his attention. With ABA they managed to get him to be sitting down, listening and learning how to repeat sounds. they got the instructional control needed and the therapy was done in an environment where he felt comfortable, at home.
i know i am not answering your question, but maybe you could give this a try.
Driving around also makes an impact on them and take a toll on us. Believe me I know.
