Co-regulation

You and your child can get to a feeling of calm and safety, together.

Overview

You can help your child learn to regulate their brain and body through co-regulation. This is when one person helps another to feel calm and safe by providing a warm and caring interaction. This is the foundation for self-regulation, when your child learns to manage how they act and feel.

When you co-regulate with your child, you are trying to get to a feeling of connection and safety together. This reduces their physical and emotional distress. You co-regulate with your child when you:

  • soothe your crying baby at night
  • encourage your preschooler on their first day at school
  • support your teen through a friendship breakdown

Window of tolerance

Your child’s brain and body are designed to keep them safe and manage challenges.

When everything is going well, your child feels regulated, or just right. They’re in their window of tolerance. In this state, they’re alert, ready to learn, playful, and connect with others.

No one can feel just right all the time. Your child will move outside their window of tolerance when their brain and body recognize a big challenge or stress. Your child may feel stress from a change in routine, a new situation, or when something doesn’t go their way.

When their brain detects too much stress, their body reacts impulsively. You may hear this called the fight, flight, or freeze stress response. This can make your child feel dysregulated, or out of control. It’s harder for them to think clearly and control their actions, feelings, and thoughts.

They’re outside their window of tolerance.

Being inside and outside of their window of tolerance are both normal and even necessary for survival. Their window of tolerance can change with time or depending on the situation.

The size of your child’s window of tolerance can grow with support and practice. It can also shrink in certain situations, like when they’re feeling hungry, tired, or sick.

You can help your child. Notice when your child moves outside their window of tolerance and help them return to feeling just right through co-regulation. Take charge in a kind way by helping them to see signs that they’re safe so they can begin to move back into their window of tolerance.
