Rain, have you ever asked your T about integration of your child and teen parts with your Self? Maybe that approach would be more helpful than just accepting them. When I did inner healing I had a bunch of parts, carrying fragments of feelings I believe, integrated and it seemed like a good thing. I'm not sure why the trend is to accept the parts rather than integrate them as it used to be. Do you know why that approach is use now?

Eta: I'm not understanding the mention of child parts being reassigned appropriate role? I thought that was reserved for the protector parts only. As I understand it the child parts need to be rescued and they then grow up and are integrated into the Self. Is giving child parts appropriate roles also part of the shift in how IFS is done now?
