To me, this book felt like it had no clear audience. The author sometimes hinted at her own experiences and I felt like knowing her story (as a memoir) could be illuminating but I didn't think the examples were terribly helpful. Other times, she seems to be directing the book at therapists in a cursory way. I can see where some people might find some of the exercises useful but, like some other readers, I was turned off by a few comments such as someone remembering their experience in the womb and treating their inner child like a separate person. I get that this last approach is a modality some are using in the field but I find it problematic.
I personally prefer books that are rich in data from analytical studies and case studies, this was written for anyone to be able to pick up and digest but it doesn't feel like a deep dive into the impact of this type of mothering (or non-mothering). If this is someone's introduction to childhood trauma or neglect, it may be helpful but, having researched these topics previously, I didn't learn anything new. That said, I want to reiterate that some of the exercises could be very helpful to some and as an introduction or a one-off on the topic, this will do the job.
