In play therapy, we don’t just see behaviour
we see the nervous system underneath it
Polyvagal Theory, first developed by Dr Stephen Porges, helps us understand how the autonomic nervous system responds to safety, danger and threat.
Building on earlier work in neuroscience and attachment, including theorists such as John Bowlby, this framework offers a relational way of understanding children’s behaviour.
We understand that children move through different states of their autonomic nervous system.
🟢 Safe and Connected (Ventral Vagal)
A child feels calm, curious and able to engage in play and relationships.
🟠 Alert and Mobilised (Sympathetic)
A child may appear anxious, restless or dysregulated and their system is preparing to fight or flee.
🔵 Shutdown and Withdrawn (Dorsal Vagal)
A child may seem flat, disconnected or disengaged and their system is conserving energy to cope.
✨ In the playroom, children don’t need to explain these states in words.
Through play, they show us where they are and gently, safely we meet them there
Play therapy offers:
💛 A regulated adult nervous system
💛 A safe, attuned relationship
💛 Opportunities for co regulation
💛 Space for the child to move back towards connection
Because healing doesn’t come from fixing behaviour.
It comes from feeling safe enough to be understood.
