My T never used the term "limited reparenting" as I think that comes from Schema Therapy, but she does refer to work we do as "reparative" or sometimes reparenting. They mean the same thing.

My opinion of it is that parenting is HARD. Reparenting is even HARDER, since you're cleaning up after someone else's mistakes, and the person is now an adult so you have no power to keep them from doing stupid stuff or up and leaving. There is great possibility to horribly screw things up and leave your client worse off than before. But if you have a T that really knows what he/she is doing, AND if you are ready for it, it can be a wonderful, deeply healing experience as it has been for me.

Also, at least for me, reparenting has never included telling me what to do. It consists mainly of modelling how to be supportive and attuned in ways my parents might not have been. Before therapy I never knew what it was like to KNOW someone was there for me in a steady, safe way no matter what.

Edit: So yes, it is a huge risk to take. I won't say don't do it, but I will say DO YOUR VETTING before you get to deep into it.
