You make a lot of a sense. However, I've seen video of this kid. The articulation is only part of the issue. He seems cognitively delayed. I don't see him speaking in the manner Parker suggest. Of course I'm not an expert like you so I don't know.<quoted text>
Unless you are a speech language therapist/pathologist, I think you are dead wrong on this one.
I have 4 children with speech/language delays of varying degrees, all which include articulation delays varying from barely enough for speech therapy to quite severe. Based off of Kate's posts on CB and the videos she's posted, I think it's safe to say that Joshua has had fairly age appropriate expressive language skills and some articulation issues, but nothing severe.
Articulation from a speech therapy viewpoint is not about vocabulary, it's about the formation of the sounds that make up words. A 6 or 7 year old saying "Don't you agree?" in proper context isn't too shocking, although from a child of that age with articulation issues, might sound like "Dun you ah-gwee".
He bottom line, though, is that we know Parker is an insane liar. She has zero credibility. His it strains logic to believe anything she ever published was true. And if the kid has said what she claims, you know she'd of had a video camera conveniently at hand to capture the moment so she could use it to bilk more people out of their cash.
