Donna,
My grandson was diagx with Apraxia also. He is pre-school/kindergarten.

So bright, never forgets a thing, but the speech was so long in coming and still not the area to keep up with Kindergarteners. He has therapy at school 30 minutes or so 2x's a week, plus the teachers work with him.

Some days I have a harder time then others with words. He just had his tonsls and adnoids out, so hoping his ear infections may have been part and going to clear up now.

It is the ability or inability of the braing to get the language from the brain to mouth properly.
I had a late talker, now 28, but he did talk finally and well, but is very quiet person.
Hope that you can find great results and good program.
