I am not reading this book, but I HAVE done the excercises with re-parenting the inner child.
I think it was easier for me since I am a parent?
I read a group online who was doing this and getting into some really powerful and healing stuff.
One thing they did with written work was to use the hand they do not normally write with...and write with that hand from the inner child.....I saw some incredible things take place!
I started talking with my child with a hi,
(tentative hi back)
how are you?
(I'm mad at you!)
can you tell me what you are mad about?
I got an earfull!
It was a great excercise and one of the key things in me learning about my feelings and taking care of me.
hope this helps.
