Question about Dr Phil Family?!?

Is The Dr Phil Family (Alexandra, Katherine, Erin, and Marty) ever going to come back on the show, even for just one episode so we can see Alexandra's baby? (due date was july 3rd), and see how the family is doing? Also, after the finale of Dr Phil family, there was a link on drphil.com that was a sign up thing for the NEXT dr phil family, where you could apply to be the next dr phil family. Are they going to have a new one? If so, when? I don't see anything about it on the website anymore :( please help!
