The part that stopped you today
might be three years old.
Until you meet it at the age it formed, no protocol will hold.

Parts from this window have no language. They communicate in sensation, in body state, in a quality of presence or absence. They cannot respond to verbal renegotiation because they predate language. The intervention has to be somatic, meeting the body in its state, offering regulation rather than conversation. Often carries intergenerational material (the epigenetic layer). The 0-3 window is also where secure or insecure attachment was installed, which means it determines what "safety" feels like in the body, for life, unless the body level is directly reached.

Facilitation approach: The Landing held for longer than usual. No verbal content until somatic stabilization is present. Sound (Frequency Seal) particularly effective here.

This window is where the most fundamental self-concept beliefs install. "I am too much." "I am not enough." "If I disappear, things are better." "I have to be good to be loved." These beliefs form from a child's attempt to make sense of family dynamics using magical thinking, where causality is based on emotion and proximity, not logic. Critically: these parts believe in their narrative with absolute certainty. They do not respond well to cognitive challenge. They respond to being met with the quality of witness they never received, unhurried, non-corrective, present.

Facilitation approach: Play language. Metaphor. Slow, prosodically warm pacing. Verbal grounding matters most at this developmental window.

The peer group becomes the primary reference at this window. Belonging is existential. Being different, excluded, or rejected at this stage produces some of the most persistent social anxiety and visibility resistance in adults. Parts from this window tend to be rule-based and fairness-oriented. They are often experienced as the part that tracks what other people think, the part that monitors for subtle signs of rejection, or the part that enforces conformity to prevent exposure.

Facilitation approach: Social framing works here. "What would the group you wanted to belong to have needed to know about you?" Belonging exercises. Parts work that restores the sense of acceptable difference.

Adolescence produces some of the most active protectors in adult psychology. The stakes, social belonging, identity coherence, autonomy from caregivers, feel life-threatening at this developmental stage because they are, developmentally speaking, close to it. The inner critic is frequently a 13-17 window part. So is the perfectionist, the people-pleaser under high stakes, and the part that self-censors before speaking in groups. These parts are often sophisticated, they use adult-sounding language, but their threat assessment is still running on adolescent stakes.

Facilitation approach: Acknowledge the sophistication. Treat the part as capable of negotiation. Ask about what was specifically at stake in the original context. The renegotiation often involves updating the threat assessment to reflect adult-level social reality.

Parts from this window often present as highly competent. They formed during the period when the person was first operating as an independent adult, and when the first major failures, betrayals, or disappointments at an adult scale occurred. These are frequently the overachievers, the self-reliant parts that refuse help, the parts that learned "I can only count on myself." Also: parts that formed around relationship betrayal during this window, which often run as the part that won't let anyone fully in.

Facilitation approach: Respect the competence, don't infantilize. Acknowledge the logic of what the part learned. Work toward updating the risk assessment: what is actually available now that wasn't available then?

Parts from this window often present as the most "reasonable", and the most resistant to parts work framing. They sound like practical concerns. "This is just how it is." "I can't afford to change this now." "Too much is at stake." These parts formed around the costs of the choices made during consolidation: the career built at the expense of other things, the relationship maintained for practical reasons, the identity constructed around achievement. They protect a version of the self that has significant sunk cost.

Facilitation approach: Lead with pragmatics, not vulnerability. These parts respond to "what would actually work better" more than "what do you need." The exile underneath is usually about authenticity, a deep knowing of what was traded away.
