The brain’s capacity to change its physical structure and functional organisation in response to experience. Far from being fixed at birth or in early childhood, the brain remains malleable; this makes the texture of everyday interactions a genuine developmental force, not mere emotional comfort.
## Everyday moments as developmental architecture
Siegel and Bryson’s framing of neuroplasticity is resolutely practical. The brain is ‘plastic, or moldable’,[^wbc-p7] which means that the quality and character of parenting moments leave physical traces. By using everyday moments, a parent can ‘influence how well your child’s brain grows toward integration’.[^wbc-p10] Ordinary dinners, bedtime conversations, and responses to tantrums are not incidental to development; they are the mechanism of it. The implication is that there is no neutral parenting: every interaction either promotes integration or works against it.
## The past is not fixed
==The claim extends beyond the developing child. The brain’s malleability means that we ‘aren’t held captive for the rest of our lives by the way our brain works at this moment’; genuine rewiring toward health and happiness remains possible.[^wbc-p7b]== Siegel and Bryson place this statement at the opening of their practical programme, before any strategy is introduced; it functions as a premise for parents as much as for their children.
