Hi there,
Issue#26
There’s a moment most toddler parents recognize. You say no — calmly, clearly — and your sweet child dissolves into a puddle on the floor. Limbs flailing. Tears flowing. Volume at maximum capacity. It feels dramatic, disproportionate, sometimes even personal.
But it isn’t.
One of the most freeing realizations for me in early parenthood has been this: toddlers are not giving us a hard time. They are having a hard time.
The first five years of life are a period of astonishing brain growth. By age five, a child’s brain reaches about 90% of its adult size. But size isn’t the same as maturity. The prefrontal cortex — responsible for impulse control, emotional regulation, and flexible thinking — is still under construction. Meanwhile, the emotional centers of the brain are fully online.
In simple terms: big feelings, limited brakes.
So when a toddler grabs a toy, refuses to leave the park, or screams because the white shoes are suddenly unacceptable, it’s not defiance in the way adults understand it. It’s a nervous system that hasn’t yet learned how to regulate itself.
Understanding that shifted something in me. It softened my reaction. But it also clarified my responsibility. Because if their internal regulation is still developing, they need something external to steady them.
That’s where boundaries come in — something I began to understand more deeply after listening to Dr. Becky Kennedy.
Boundaries aren’t punishment. They aren’t control. In early childhood, they are scaffolding — sturdy railings that help a young child feel safe while their regulation skills are still forming.
In all honesty, there are still days when I’m tempted to give in just to avoid the meltdown. Days when I question whether holding the line over something small — one more book, no snacks before dinner, shoes must stay on outside — is worth the tears.
But I remind myself: consistency builds predictability. Predictability builds security. And security builds emotional resilience.
When I kneel down and say, “I know you’re upset. We’re still leaving the park,” I’m doing two things at once. I’m validating the feeling and holding the boundary. Both matter.
Over time, children begin to internalize a powerful rhythm:
My feelings are allowed.
Not all behaviors are.
That distinction is foundational. It teaches them that emotions are safe — but actions have limits. And something surprising happens when we stay steady: boundaries actually deepen connection. When expectations are clear, there’s less negotiation and more trust. He may protest in the moment, but over time he leans into the predictability. Bedtime follows the same rhythm. We leave when we say we will. Hitting is never okay. Feelings always are.
In a world that feels big and overstimulating, that steadiness becomes an anchor. It’s also why boundaries aren’t just for our children. They’re for us.
Holding limits around screen time. Around sleep. Around how others speak to us in front of our child. When we model self-respect and clarity, we quietly teach it.
I believe early childhood isn’t about perfect compliance. It’s about co-regulation — lending our calm nervous system to a child whose system is still learning. Over hundreds of small, ordinary interactions, they borrow our steadiness until they begin to build their own. Every consistent boundary, every repaired moment, every calm “I know you’re upset” is quietly shaping that invisible architecture.
One thing to try this week
Choose one recurring friction point — leaving the house or cleaning up toys — and decide on a clear, simple boundary. State it calmly. Repeat it consistently. Pair it with empathy: “It’s hard to stop playing. We’re cleaning up now.” Resist over-explaining. Toddlers need clarity more than reasoning.
Notice what changes when the message stays the same.
Before you go
Is there a boundary you’re currently struggling to hold? Or one that, once you stayed consistent, made life noticeably calmer?
Hit reply and tell me. I read every single one.
Until next time,
