Trauma, Boundaries, and the Battle for Safety

To Set Appropriate Boundaries, You Must Have an Experience of Safety


Children who have experienced developmental trauma (in the womb or in early childhood) have an over-active arousal system. This means that even if they are safe, they don’t feel safe. This lack of understanding what “safe” feels like creates lots of boundary issues as they get older. 


The Under-Boundaried Kid


“I feel like I can’t let my kid out of my sight.”

“My kid would follow someone off a cliff.”

“My kids would try any substance that was given to them. They literally have no sense of independence or safety.” 


These are the types of phrases I hear from parents with under-boundaried kids. These kids do generally well in the right environment, but if there are rotten apples in the bunch, they join them quickly in whatever activity they are engaging in. They may stay out of trouble until they get a phone, and then they begin to unravel at that point. 


The Over-Boundaried Kid


“My child is always ready to fight.” 

“Honestly, I hate to ask anything of her. I would rather do it myself than deal with her attitude for every small request.”

“My kiddo bosses everyone around. I am shocked he still has any friends.” 

“She doesn’t care if she breaks our rules or makes us upset.” 

“He just does whatever he wants.” 


These are some phrases I hear from parents of over-boundaried kids. These kiddos often avoid safety and seek danger out. Safety feels unfamiliar to them. Safety feels boring and eerily peaceful. Yes, kids can also move back and forth between being over-boundaried and under- boundaried as well, which is extra complicated. 

Help Your Child Recognize or Find Safe Spaces


Setting boundaries in the right way and at the right time is a very sophisticated skill.  I don’t expect any child or teen to do it very well, but we at least want them to start to recognize when it is necessary.  We can help our kids pay attention to the friends that make them feel better about themselves.  We can point out that every time they spend time with next-door Joey, they get in trouble.  We can demonstrate safe boundaries and talk through them with our kids.  We can point out the times and spaces where  kids are the most regulated and enjoyable.  We can create opportunities for more spaces like these for our kids.  This process will take time, years actually. It can’t be rushed, and it can’t be learned with lectures.  We have to understand what a healthy relationship looks like and be able to participate in that relationship in order to move toward healthy boundary setting.  

As a parent, I have spent years being afraid
By Melody Aguayo December 19, 2025
As a parent, I have spent years being afraid. Too much of my parenting was driven by fear—shaping my decisions, tightening my grip, and setting the emotional thermostat of our home. I didn’t know how to stop being afraid, because the things other parents only worried might happen? They were actually happening to our c
navigating a labyrinth without a map

Parenting or teaching trauma-impacted children can feel like navigating a labyrinth without a map. The behaviors we see are often confusing, frustrating, or overwhelming—and it’s tempting to assume that these kids are acting out on purpose.
Children who come from early adversity or chronic stress
By Melody Aguayo December 5, 2025
Children who come from early adversity or chronic stress grow up in environments where their nervous systems are constantly trying to survive. Because of this, they receive a steady stream of confusing, conflicting messages—messages that shape how they see themselves long before they can put words to the pain.
A hug from a tired mom

“I know it sounds ridiculous,” she said softly, “but I worry about everything.” A mom with tired eyes sat across from me, explaining why she refused to leave her child with anyone—even for a moment of respite.

Parenting and Adoption Trauma

Even God Wanted a Peaceful Home My husband loves peace. When we first got married, I wondered what on earth was wrong with him. It was like he just refused to argue with me. I think it was partly my age (19) and partly my personality, but I actually enjoyed a bit of conflict here and there. If someone offend
Understanding and Supporting School Refusal
By Melody Aguayo October 24, 2025
There’s a certain kind of panic that rises in a parent’s chest when their child begins refusing school. It starts with small things—complaints about stomachaches, missed assignments, growing resistance to waking up—and before you know it, the morning routine has become a daily battle.
You will have seasons of coasting through the sky.

Dear Little Mama, Stop looking for the final landing strip of this parenting journey—it doesn’t exist. I know you think it does. You see airplanes landing all around you… safely, smoothly, touching down on milestones and achievements you can only imagine.
how to handle verbal rejection
By Melody Aguayo September 19, 2025
That’s such an important (and painful) question. When a trauma-impacted child rejects a parent—whether through words, behaviors, or distance—it can cut deeply.
A teenager in the grips of psychosis
By Melody Aguayo September 12, 2025
One of the most painful contradictions in our mental health and justice systems lies in the way we treat teenagers struggling with severe mental illness, including psychosis. On one hand, these young people are granted civil rights that allow them to refuse psychiatric medication—even when their judgment is deeply impa
