I found this book really well, the explanations are clear and accessible: each difficulty (he does not eat, he said bad words, etc.) a drawing shows the situation where one feels sometimes blocked, felt of the child and explain its development and how it could get out of trouble by respecting her child. it does not seem very clear as that, but it is the and it gave me lots of tracks m not bogged down in unnecessary conflicts ...
One of the tips that I have learned and I try to apply is to ensure "love tank" of my son. If returning in the evening, I take 15 minutes to devote myself to him, playing, talking, etc. then I observed a clear difference: it feels like, "her love tank is filled," so he will play only later much easier.
To read urgently to learn to express themselves differently and to accompany her child with respect and love!
