My son is 2 yrs old and was 12 weeks early at birth. While he has done exceptional for being a preemie, he is presently nonverbal due to an (almost certain) oral-motor disability that keeps robbing him of his speech. (We will have the official diagnosis within a couple weeks.) He is very high with receptive language as well as cognitive and completely passed the communicationl part of the Early Intervention assessment even without speech (which is hard to do), so he is definitely compensating for his lack of speech.
I am working with him to learn signs and develop the PECS system for communication, mainly because he wants to communicate more complex things than signs presently give him. We do awesome for me figuring out his wants, needs, communications, etc. But I have to tell you, it is tiring my brain to figure out this kid sometimes.
So my question is this ---- how do you keep challenging a kid who can't talk back? I've been troubled by this. When my son shrieks "hey" (his word for everything) and points, he's pointing at a front-end loader. Now, I don't know if "hey" means "check that out", "look, Mommy, I found another one!" or something deeper like "Why does it have that thing underneath the cab? And what is it called?" Would you keep describing the front end loader and all the parts and how they work or would you back up and wait for his language to develop. I don't want to overwhelm him, but my son can practically look at, play with, and sit on anything with wheels, all day long. He is THAT interested. What would you do?
