Recommend a book on speech dyspraxia, please. :)

DS is in speech therapy, but doesn't have a specific DX beyond speech delay. I tend to think he may have dyspraxia, based on the little understanding I have of it. I want to understand more so I know how to support his communication on a daily basis.

He is 3.5, speaks in 1 to 2 word phrases, and has trouble answering direct questions. He does much better spontaneously vocalizing and singing.

Thanks for any resources you can suggest!

"Speaking of Apraxia" is what I am reading now and so far has been great!
