Thank you to everyone who posted. It is always good to hear stories that give hope and all your children sound amazing. One other comment I will say about the evaluation with the Speech pathologist, DS was very non-compliant. He was LOVING the room and was making up his own little games but would not point to any pictures she showed him, or even pick out a specific toy among a few choices. Luckily, the therapist immediately saw it as a compliance issue rather than an ability issue. She kept searching for things that would motivate him to speak. She also said because he has overall good communication (just not through words!) she thought just a few months of therapy would jump start his talking.
And wayoutwest, you are right, if he is four before we have a conversation with him it will be ok, but there is a lot of anxiety in the meantime!
Thanks,
