I don't know much about Mort's program, but I can tell you that doing stuff together as a family is the best way to start off. It doesn't feel like pressure, you both get to have fun with your son and the opportunity to talk & spend time together is always there.
This is such a 180 for your W - really happy for you. It sounds like your going to do this anyway, but my only advice would be to take it slow, validate your W as much as possible and really listen to her.
Great news Snow - keep us posted!!
