Learning How to Contain Feelings

Developing Emotional Regulation Through Co-Regulation

“Children don’t learn to manage big feelings by being told to calm down. They learn by feeling those feelings while held emotionally by a calm adult.” — Philippa Perry

The Developmental Task of Emotional Regulation

Babies are born with no ability to regulate their emotions. When they feel hunger, discomfort, or fear, they’re completely overwhelmed by it. They need adults to help them return to calm—through feeding, soothing, rocking, or simply holding them.

This external regulation gradually becomes internal regulation. Over years of being helped to calm down, children develop the neural pathways and skills to manage their own emotions. But this isn’t a switch that flips at a certain age—it’s a gradual development that requires thousands of experiences of being emotionally “contained” by adults.

Perry explains that “containment” means holding space for a child’s big feelings without being overwhelmed yourself, without trying to shut the feelings down, and without making the child’s emotions about you. It’s the foundation of emotional intelligence.

What Is Emotional Containment?

Containment is the process by which an adult takes in a child’s overwhelming emotion, processes it internally, and returns it to the child in a more manageable form.

It looks like this:

Child’s experience: Overwhelmed by big feeling (rage, terror, despair)

Adult’s response: Stays calm, names the feeling, validates it, provides soothing presence

Child’s internalization: “This feeling is intense but not dangerous. I can survive it. An adult can help me through it.”

Over time: The child develops the capacity to do this for themselves—to feel big emotions without being completely dysregulated.

Containment is NOT:

Containment IS:

The Neuroscience of Co-Regulation

Young children literally cannot calm themselves down when highly activated. Their prefrontal cortex (the part of the brain that regulates emotion) is still developing and won’t be fully mature until their mid-twenties.

They need co-regulation: an adult’s calm nervous system helps regulate theirs.

When you stay calm in the face of your child’s big emotions, your regulated nervous system sends safety signals to theirs. Your calm breathing, steady voice, and relaxed body language communicate: “You’re safe. This will pass. I’ve got you.”

Over thousands of repetitions of this experience, children internalize your regulation and develop their own capacity to self-soothe.

If you get dysregulated when they’re upset:

The Container Metaphor

Perry uses the metaphor of a container. Your child’s big emotion is like water poured into a container. If the container (you) is solid and stable, it can hold the water (emotion) without spilling. The child sees their overwhelming feeling contained and survivable.

If the container cracks or overflows (you get upset, anxious, or angry in response), the water spills everywhere. The child learns: my feelings are too much. They break things. No one can help me with them.

Your job is being a strong container—not making the feelings go away, but proving they can be held.

How to Contain Big Feelings

Containment is a skill that requires practice, especially if you weren’t emotionally contained as a child. Perry offers concrete strategies.

The Containment Process

1. Notice your own reaction: When your child melts down, check your internal state. Are you calm? Anxious? Angry? Overwhelmed?

Take a breath. Ground yourself. You need to regulate yourself before you can help them.

2. Get physically present: Get down to their level. Make eye contact if they’ll accept it. Be near them (unless they need space).

Your physical presence communicates safety.

3. Stay calm: Keep your voice steady and warm. Slow your breathing. Relax your body. Your nervous system is the anchor.

4. Name the feeling: “You’re feeling really angry right now.” “This is frustrating for you.” “You’re scared.”

Naming emotions helps children understand what they’re experiencing and that feelings are manageable.

5. Validate without judgment: “It’s okay to feel angry.” “I understand. That would upset me too.” “Your feelings make sense.”

You’re not saying the behavior is okay—you’re saying the feeling is acceptable.

6. Be the steady presence: Don’t rush them to calm down. Don’t lecture. Just be there, calm and accepting, while they feel.

“I’m right here. You’re safe. This feeling will pass.”

7. Help them return to regulation: Offer comfort when they’re ready: a hug, deep breaths together, a drink of water.

8. Reflect afterward (when calm): “That was a really big feeling. You were so mad. But you got through it, and I was with you.”

Age-Specific Containment

Babies (0-12 months): They need immediate physical soothing. Hold them, rock them, use a calm voice, meet their needs. They’re building basic trust that adults will help when they’re distressed.

Toddlers (1-3 years): Big emotions, limited language. They need you to stay close, name feelings simply, and ride out tantrums without punishment. Physical containment (holding if they allow it) helps.

Preschoolers (3-5 years): Growing language allows more emotional coaching. Name feelings, validate, offer simple strategies: “When you’re mad, you can stomp your feet or hit this pillow instead of hitting your brother.”

School-age (6-11 years): They can start understanding their emotions with more nuance. After containment, you can discuss triggers, coping strategies, and problem-solving. But containment still comes first.

Teenagers: They need space for big feelings but also reassurance you’re available. Contain by staying calm, validating, and not taking their emotions personally. “I can see you’re really upset. I’m here if you want to talk.”

When Containing Feels Hard

Containing your child’s emotions can trigger your own uncontained childhood feelings. If your parents didn’t help you with big emotions, being present for your child’s can feel overwhelming.

Common blocks to containment:

Your feelings were dismissed or punished: Your child’s big emotions trigger your own suppressed feelings. You reflexively shut them down the way you were shut down.

You fear losing control: If emotions felt dangerous in your childhood, your child’s intensity feels threatening. You need them to calm down so you can feel safe.

You were parentified: If you had to manage your parents’ emotions, your child’s neediness feels like too much. You want them to self-soothe because you had to.

You’re depleted: If you’re burnt out, exhausted, or under-resourced, you simply don’t have the emotional bandwidth to contain anyone else’s feelings.

Self-Compassion for Hard Moments

When you can’t contain effectively:

You will have moments when you can’t be the container—when you’re too dysregulated yourself, too exhausted, or too triggered.

That’s okay. You’re human.

In those moments:

Teaching Self-Regulation Through Containment

The paradox: children learn to self-regulate through being other-regulated first. You can’t teach self-regulation by demanding it (“Calm down!”). You teach it by providing it.

As children are repeatedly contained:

Eventually, they can contain their own feelings. But that skill takes years to develop.

Example: Containing a Tantrum

Situation: Your 4-year-old is having a massive meltdown because their sandwich was cut wrong.

What doesn’t help: “Stop being ridiculous! It’s just a sandwich!” “You need to calm down right now!” “Fine, go to your room until you can behave!”

What helps (containment):

To an outside observer, it seems absurd to validate rage over a sandwich. But it’s not about the sandwich—it’s about learning to feel and survive big emotions with support.

The Long-Term Benefit

Children who are consistently contained develop:

Adults who weren’t emotionally contained often struggle with:

Containment is preventative mental health care. You’re building your child’s capacity to navigate the emotional complexity of being human.

Reflection

Think about the last time your child had big emotions. Were you able to contain them, or did you get dysregulated? What would have helped you stay calm? What support or healing do you need to be a better emotional container?

The Container Needs Filling

You cannot pour from an empty cup. To contain your child’s emotions, you need your own emotional needs met.

Take care of yourself:

Containment isn’t martyrdom. It’s being resourced enough to be a steady presence for your child.
