I would check with the Erickson Listserv. See above for information. You might also check with the hypnosis listserv. For information contact Irving Kirsch irvingk@uconnvm.uconn.edu.
I think one could look at the systemic changes, too. A new child makes quite a difference in the couple's dynamic.
Good luck! See you at the Brief Therapy Conference in NY in August
