Imagine the brain as a house with two floors. The downstairs contains the basic functionsâthings that happen automatically and keep us alive. The upstairs contains the more sophisticated functionsâthe things that make us truly human.
Children's challenge: the upstairs isn't finished being built. And even in adults, the upstairs can temporarily "go offline" under stress.
The downstairs brain is primitive, reactive, and fully online from birth. Itâs designed to keep us alive, not to be reasonable.
The upstairs brain is sophisticated, thoughtfulâand under construction until the mid-20s.
Dr. Siegel uses the metaphor of âflipping your lid.â Make a fist with your thumb tucked inside your fingers. The thumb is the downstairs brain; the fingers folded over are the upstairs brain.
When we get very upset, the fingers fly upâthe upstairs brain goes offline. Now only the downstairs brain is running the show. This is why you canât reason with an extremely upset child (or adult): the reasoning part is temporarily disconnected.
Not all tantrums are created equal. Understanding the difference between upstairs and downstairs tantrums changes how you respond:
The child has completely âflipped their lid.â They are overwhelmed, flooded, and the upstairs brain is offline.
What to do: Connection, safety, comfort. This is not a teaching momentâitâs a nurturing moment. Wait for the brain to regulate before any discussion.
The child is making a choice to throw a fit. The upstairs brain is still engagedâtheyâre being strategic.
What to do: Set clear limits. Donât negotiate with terrorism. The child can stop if they choose toâand they will if the tantrum isnât working.
Ask yourself: Is my child capable of stopping right now if I offered something they really wanted? If yes, itâs likely an upstairs tantrum. If noâif theyâre so flooded they couldnât stop even if they wanted toâitâs a downstairs tantrum.
Appeal to the upstairs brain. Ask questions that invite thinking: âWhatâs another way you could handle this?â Avoid triggering the downstairs brain with threats, yelling, or harsh punishment.
The goal: Keep the upstairs brain online so your child can make good decisions.
This triggers the downstairs brain. Now the child is in fight mode, focused on the conflict, not the homework.
This engages the upstairs brain. The child feels supported and can think about the actual problem.
The upstairs brain develops through use. Give your child lots of opportunities to exercise it: make decisions, manage emotions, consider othersâ feelings, negotiate, plan.
The science: Neural pathways strengthen with use. The more the upstairs brain practices, the stronger it gets.
You canât expect a child to have good self-control, empathy, or decision-making skills if they never practice them. Here are ways to exercise the upstairs brain:
Decision-making: âWould you like to wear the red shirt or the blue shirt?â
Emotional regulation: âYou seem really frustrated. What could help you calm down?â
Empathy: âHow do you think your sister felt when that happened?â
Planning: âWhat do you think will happen if you do that?â
Ethics: âWas that fair? What would be the right thing to do?â
Body control: Games like freeze dance, Simon Says, or any activity requiring impulse control
The connection between upstairs and downstairs brain is like a staircase. Integration means the two floors are well-connectedâemotions from downstairs can be regulated by thinking from upstairs, and decisions from upstairs are informed by emotional signals from downstairs.
Your job is to help build this staircase through daily interactions.
When your child is stuck in a negative emotional state, physical movement can shift their brain state. Running, jumping, walkingâany movement can help restore balance between upstairs and downstairs.
The science: Physical movement changes body chemistry and brain state, often shifting us out of stuck emotional patterns.
Or for younger children: âLetâs have a dance party!â or âRace you to the mailbox!â
After physical activity, the childâs brain state has shifted, and theyâre often more regulated and receptive.
Parents flip their lids too. When youâre exhausted, stressed, and your child pushes your buttons, your upstairs brain can go offline. You might yell, threaten, or do things you regret.
What to do:
Expecting a child to consistently control their impulses, think ahead, and regulate their emotions is like expecting someone to run a marathon before they can walk. The upstairs brain wonât be fully developed until the mid-20s.
Your patience nowâand the opportunities you provide for practiceâare literally building your childâs brain architecture.
