I bought this book (recommended by the PMI) in the hope of learning how to separate me gently from my daughter. (I keep it for 14 months and she has trouble falling asleep alone). "Untie me," returned no index, track or practical idea, but tells stories (often quite harsh) of different cases which we only know the beginning and the end rarely. This book does not fit what I was looking for. It is well written, easy to read, nice but I often stayed on my hunger for knowledge and understanding.
