About Sonja

I’m an experienced positive behaviour support consultant, specialising in trauma-sensitive practice and staff wellbeing.

I work together with school teams and care teams to help children get back into learning. I offer supportive and educative supervision for staff working with school-aged children and young people. I focus on vicarious trauma prevention, trauma sensitive practice and positive behaviour support.

Positive Behaviour Support

Two boys illustration

Positive Behaviour Support (PBS) provides a framework to help schools to build and maintain safe and orderly learning environments.

PBS provides systems to support staff behaviour, data to guide decision-making and research-based practices to support student behaviour.

Positive behaviour support is a set of research-based strategies used to increase quality of life and decrease problem behaviour by teaching new skills and making changes in a person’s environment. (apbs.org)

Trauma sensitive practice

Trauma sensitive practice focuses on being safe and feeling safe. Its goal is to restore a sense of safety, in environment, relationship, body and mind. Once calm, we can connect, learn and build resources for resilience and wellbeing.

    The purpose of this resource is to increase awareness of different ways of being with ourselves and others. Informed by the window of tolerance (Ogden & Fisher, 2015) and polyvagal theory (Porges, 2011), this Wellbeing Reflection offers a continuum of states, from being present, to being entangled, to being avoidant. It invites us to notice where we are, and what we need, so we are better able to offer support to ourselves and to others. … read more
