Do you feel like you are always walking on eggshells to prevent a blowup at home? Does a child's behaviour come out of the blue? Child psychologist Mona Delahooke explains all of these things to us. Delving into Polyvagal Theory and past over-simplified "checklist" behavioural medicine, Mona urges us to see behaviour in a deeper and more holistic way. Once we understand where a child's behaviour is coming from, then we can start to address it in a meaningful way. The science of children's behaviour is shifting and it is vital we grasp this if we want to help children grow up to be resilient and empathic, and live meaningful lives.
