Window of Tolerance in Play Therapy: Why Kids "Bail" on Deep Play
Cathi Spooner 
Learn why shifts in play may be signs of self-regulation, not avoidance, and what they reveal about a child's window of tolerance.
How neuroscience, attachment, and co-regulation can help you understand what’s underneath big emotions and decide what to do next
Have you ever been 20 minutes into a play therapy session when it feels like your client is finally getting somewhere?
Maybe there's an intense sword battle happening.
You've been chained up.
The good guys and bad guys have been fighting it out for the last 15 minutes.
Or maybe a child whose parents are going through a divorce has been moving figures back and forth between two dollhouses.
The play feels deep.
And then...
They're done.
Suddenly they want Play-Doh.
Or they start drawing.
Or they wander over to the kitchen and start making you dinner.
And you're sitting there wondering:
Wait. What just happened?
Did we get too close to something?
Are they avoiding the difficult stuff?
Are they resistant?
Should I redirect them back to what they were doing?
Or maybe you start questioning yourself.
Is this even working?
I want to offer you another possibility.
Maybe that shift isn't avoidance at all.
Maybe the child is using the play therapy process exactly the way they need to use it.
Maybe they're recognizing—without necessarily being able to verbalize it—that they've reached the edge of what they can tolerate emotionally in that moment.
And shifting into another kind of play may be how they stay within their window of tolerance.
Children Can't Stay in Deep Emotional Work for 45 Minutes Straight
Think about traditional talk therapy with adults.
Even adults don't usually spend an entire therapy session at maximum emotional intensity.
There are ebbs and flows.
We move toward something difficult.
We pull back.
We talk about something less intense.
We pause.
Then maybe we move toward the difficult material again.
Children do this too.
But instead of necessarily telling us:
“That was emotionally intense. I need to take a break before I continue processing it.”
they show us through play.
That's why we have to learn how to read what is happening in the playroom.
Forty-five to 60 minutes of therapeutic play can be a lot for a child.
So when they suddenly shift activities, the question isn't automatically:
“Why are they avoiding this?”
A better question might be:
“How is this child using play to manage the intensity of what they're working through?”
Trusting the Child's Capacity to Lead
This connects to something we talk about a lot in play therapy: the child's capacity to lead.
We're trusting that children have an innate capacity to move toward healing and wholeness when they're given a free and protected space in which to do that work.
Generally, the younger the child, the more we're going to follow rather than lead.
But I think we can extend that idea further.
Older children, teenagers, adults, and even families often have an internal sense of what they need too.
They may not be able to articulate it.
That's where our attunement matters.
When we learn to read our clients' cues, we can begin noticing what they're ready for, how much they're able to tolerate, and when they need something different.
Following the child doesn't mean we never set boundaries.
It doesn't mean the therapist disappears from the process.
We're still there.
We're still holding limits when necessary.
We're still co-regulating.
We're still using our theoretical model.
But we can step away from the idea that we have to control every moment of the therapeutic process in order for therapy to be working.
Some Kids Ramp Up. Some Ramp Down. Some Shift.
Children don't all show us overwhelm in the same way.
Some children ramp down.
Others ramp up.
I remember when my own kids became tired, cranky, and overwhelmed, they didn't necessarily slow down.
They got more activated.
Their bodies were everywhere.
Then came the meltdown.
We can see similar differences in the playroom.
One child may withdraw when they're reaching their capacity.
Another may become louder or more physical.
Another may start testing limits.
And another may simply change what they're playing with.
Our job is to begin recognizing that child's cues.
What does increasing intensity look like for them?
What happens when they're approaching the edge of their window of tolerance?
And what do they do to bring themselves back?
Those subtle patterns can tell us a tremendous amount about how the child is using the therapeutic process.
A Board Game Can Tell You More Than You Think
Here's an example.
I'm not a big fan of board games.
I'll play them when I believe they're therapeutically useful, but they're definitely not my favorite thing to do in the playroom.
Now imagine I'm playing a board game with a child who struggles with frustration tolerance and impulse control.
And I like to think about my moves.
I consider my options.
I do a little contingency planning.
For a child who has difficulty waiting, that can be frustrating.
But this child is hanging in there.
We're halfway through the game when suddenly, while I'm thinking about my move, they start fiddling with the game pieces.
Then they say:
“I don't like when people take a long time.”
How do we interpret that?
Is the child being impatient?
Are they complaining?
Are they being a bad sport?
Or...
Are they regulating?
Maybe manipulating the game pieces is providing sensory input while they wait.
And instead of becoming overwhelmed and throwing the board across the room, they actually verbalized what was happening:
Waiting is frustrating for me.
That's progress.
The child experienced frustration, found something to do with their body while they waited, stayed in the game, and communicated what was difficult.
That's a child working to stay within their window of tolerance.
What If Switching Activities Is Part of the Work?
Now let's go back to that child whose parents are divorcing.
Maybe there are two dollhouses in your playroom.
The child spends part of the session engaged in emotionally intense play between those houses.
Then suddenly they're finished.
They walk over to the Play-Doh.
They squish it.
Roll it.
Manipulate it for a while.
Then they move into some nurturing play with dolls or start cooking food in the play kitchen.
It would be easy to think:
We were getting somewhere, and then they bailed.
But look at the sequence differently.
They moved into difficult emotional material.
The intensity increased.
Then they shifted into something tactile and soothing.
Then perhaps they moved toward nurturing play.
What if that isn't a detour from the therapeutic work?
What if that is the therapeutic work?
The child may be approaching emotionally painful material, pulling back when it becomes too much, using the sensory experience of Play-Doh to regulate, and then moving into nurturing play before they're ready to approach something difficult again.
If we're too quick to redirect them back to the "important" play, we may actually interrupt the child's attempt to regulate themselves.
Your Presence Is Part of the Regulation
There's another important part of this process:
You.
Your attuned presence in the playroom can be a source of co-regulation.
That means I'm paying attention to what's happening inside myself too.
What am I feeling?
What's happening in my body?
What thoughts are coming up?
Am I becoming anxious because the child's play has become intense?
Am I frustrated?
Am I uncomfortable with what I'm seeing?
Am I feeling pressure to do something because I'm worried therapy isn't working?
And then I have to ask:
Is this mine, or am I picking up on something happening with my client?
Attunement means I'm using my whole self to remain connected and present.
Even when the child becomes frustrated.
Even when they're angry.
Even when they're testing limits.
And yes, even when they try to shoot me in the face with a Nerf dart.
I have limits around that one.
Following the child doesn't mean there are no boundaries.
It means I'm able to stay regulated enough to notice what's happening, hold the therapeutic space, and respond intentionally instead of reacting from my own discomfort.
Watch the Rhythm of the Play
When you're trying to determine whether a child is avoiding something or regulating themselves, don't just look at the activity they're doing right now.
Look at the rhythm of the session.
What happened before the shift?
How intense was the play?
What did they shift toward?
What happened after that?
Do they eventually return to more emotionally charged material?
Maybe you see a pattern like:
intense play → soothing play → nurturing play → intense play.
That rhythm gives you information.
You're watching how the child approaches emotional material, how they manage the intensity of it, and how they use the resources available in the playroom to stay within a tolerable range.
Those shifts can also help you understand whether the child is beginning to develop greater self-regulation and whether they're able to use you for co-regulation.
This is one of the ways we begin recognizing progress that might otherwise be easy to miss.
Sometimes You Won't Know What the Play Means
I've been doing this work for more than 30 years, and there are still moments when I think:
I don't know what just happened.
And that's okay.
Sometimes my job in the moment isn't to completely understand everything.
My job is to stay present.
Stay regulated.
Use my play therapy skills.
Follow my model.
And hold the therapeutic space.
I can figure it out later.
Sometimes it becomes clearer when I'm writing my progress notes.
Sometimes I talk it through with another play therapist.
Sometimes another person notices something I couldn't see because I was too close to it.
But I don't have to interrupt the therapeutic process because I don't understand what's happening yet.
That's where trusting the process becomes important.
If I'm using my play therapy model the way it's intended to be used and trusting the child's capacity to move toward healing, I can allow the process to unfold without needing to control every moment.
Your Own Window of Tolerance Matters Too
Of course, we're human.
There are things children do in the playroom that irritate us.
I still notice this in myself.
Maybe I've lost the game for the tenth time.
The rules have changed again.
And I notice myself thinking:
Seriously? How many times can I lose this game?
That's when I have to catch myself.
This isn't about me.
What does my model say?
Follow the model.
That requires congruence.
I need to recognize what's happening internally so that I can return to a place where my external responses genuinely reflect empathy, unconditional positive regard, and attunement.
We can't co-regulate effectively if we're completely dysregulated ourselves.
And we can't respond intentionally if we're unaware of what's happening inside us.
So part of becoming a skilled play therapist is learning to read our own cues just as much as we're learning to read the child's.
The Shift May Actually Be the Path
This is the part I really want you to remember.
When a child shifts away from emotionally intense play, don't automatically assume they've taken a detour.
Maybe that's the path.
Maybe moving toward something soothing is exactly what allows them to remain engaged in the therapeutic process without becoming overwhelmed.
Maybe your ability to remain attuned, present, and regulated while they do that is helping them experience something different.
I remember watching a child doing incredibly intense trauma work in a play therapy session.
Then the child suddenly shifted.
They moved into something completely different—something nurturing and soothing.
My reaction wasn't:
They're avoiding the trauma.
It was:
Of course. That was intense. Now they need some nurturing.
That child was using the play therapy environment to meet a need.
They were doing difficult emotional work and then finding a way to regulate afterward.
That's not necessarily resistance.
That can be a child who is learning to recognize what they need and use the therapeutic space to help themselves get there.
When Should the Play Therapist Step In?
There are absolutely times when we lead.
There are times when we set limits.
Depending on your play therapy model, there may be times when you introduce a directive activity or intentionally help the child move toward something more regulating.
The important question is:
Why?
Why am I stepping in?
Is it because my case conceptualization and play therapy model tell me this child needs additional co-regulation right now?
Am I noticing cues that tell me they're struggling to down-regulate on their own?
Or...
Am I stepping in because I'm anxious that therapy isn't working?
Those are very different reasons.
Before introducing another activity or redirecting the child, check in with yourself.
Are you responding to the child's needs?
Or are you responding to your own discomfort with not knowing exactly what's happening?
Your model should help guide that decision.
Maybe It Isn't Resistance at All
So the next time a child shifts activities right when the play seems to be getting deep, pause before labeling it avoidance.
Look at the whole picture.
What happened immediately before the shift?
What did they move toward?
What is their body doing?
What are they saying?
How intense was the play?
What happens next?
And how are they using your presence?
The child fiddling with game pieces while waiting for your turn may not be rude or impatient.
They may be finding a way to tolerate frustration.
The child moving from intense trauma play to nurturing dolls may not be avoiding the work.
They may be regulating after doing the work.
And the child bouncing between toys during their first few sessions may not be failing to engage in play therapy at all.
Maybe they're still figuring out whether this strange new room—and this strange new adult—are safe.
Moving from activity to activity may actually be helping them tolerate being there long enough to develop that sense of safety.
They may already be using the playroom therapeutically.
It just doesn't look the way you expected it to look.
Learn to Read the Cues Before You Try to Change Them
There's so much information available to us in the playroom when we learn how to watch for it.
Notice what the child was doing before the shift.
Notice what they shift toward.
Notice their words.
Notice their body.
Notice the intensity.
Notice what happens inside you.
And notice how they're using the relationship with you.
Over time, those patterns can help you understand how the child regulates, what may push them toward the edge of their window of tolerance, how they're using co-regulation, and whether their capacity to manage difficult emotional material is beginning to change.
Learning to recognize those subtleties takes time.
It also requires learning to trust yourself.
Because ultimately, we're building two kinds of trust in the playroom:
The child's ability to trust us—and our ability to trust ourselves and the therapeutic process.
You Don't Have to Figure Out the Playroom Alone
This is exactly the kind of clinical thinking we work through inside Play Therapy Elevation CIRCLE and Play Therapy Academy.
Sometimes it's hard to know what you're looking at when you're the only person in the room.
Having other play therapists think alongside you can give you another perspective and help you recognize things you couldn't see on your own.
Inside Play Therapy Elevation CIRCLE, we focus on that ongoing community and clinical support. We have consultation opportunities and a monthly book club where we dig into professional play therapy literature and then discuss how it actually applies to the clients we're seeing.
Right now, we're digging into play therapy themes—another area that can take a long time to feel confident identifying and understanding.
Enrollment for PTEC is currently closed, but you can join the waitlist through Renewing Hearts Play Therapy Training to be notified when it opens again.
If you're looking for something more intensive, Play Therapy Academy goes deeper into skill-building and learning how to confidently use a play therapy model throughout the stages of therapy. It's a smaller program and can also support therapists pursuing their Registered Play Therapist credential.
If you're not sure which one fits what you need, you can schedule a 30-minute video call with me through Renewing Hearts Play Therapy Training, and we'll figure it out together.
