Although “Hardwiring Happiness” is not specifically an Inner Child text it talks about the Neuroscience of the brain (trust me it is very readable) and I believe gives a scientific explanation for why some the the Inner Child Work, especially some of the Inner Child Imagery work, can have a powerful effect. This is because “neurons that fire together, wire together”. It uses HEAL: Have a positive experience. Enrich it. Absorb it. Link positive with negative.
Here is an extract from the book: “Hardwiring Happiness: How to reshape your brain and your life“
Here is an exercise in HEAL . Print it off and have a go.
