I have a friend new to AP parenting with her new little bub. But she also has two children from a previous marriage, ages 12 and 14, with whom she did CIO. She is feeling terribly guilty about it now, though her kids seem fine. She asked me for a recommendation on any reading she could do about how it is possible to move on with an attached relationship after actively pursuing CIO. Does this bring any readings to mind for you? She has enjoyed Liedloff's "Continuum Concept" and is rather philosophically-minded.
