Baby Brain: A Brave, Blisteringly Honest Triumph
Some performances earn the word brave as a hollow compliment. Baby Brain earns it in its truest, most unflinching sense. Kimberley Nixon’s one‑woman show at Porters tonight was a raw, darkly comic, emotionally disarming journey into postpartum psychosis that left the audience laughing, crying, and—crucially—understanding. It is a piece that doesn’t just tell a story, it immerses you in a mind unravelling, re‑raveling, and unravelling again.
A performance that holds nothing back
Nixon’s portrayal of Cass is astonishing in its precision and vulnerability. One moment she’s delivering razor‑sharp stand‑up, the next she’s plunging the room into the cold, disorienting terror of intrusive thoughts and delusion. The juxtaposition is brutal by design. As the press release notes, the show “breaks the fourth wall, playing with theatrical form to immerse audiences in Cass’s struggle to distinguish reality from delusion” , and that is exactly what it achieves.
“Baby Brain is a brave, blisteringly honest piece of theatre that leaves you laughing, devastated, and profoundly changed.”
The shifts between comedy and catastrophe are so stark that the audience is left suspended between laughter and heartbreak. At times, the room didn’t know whether to exhale or hold its breath. That emotional confusion is the point: Baby Brain makes you feel the instability Cass lives inside.
One of the most striking things about the performance is how Nixon uses humour not as a shield, but as a scalpel. The comedy doesn’t soften the darkness—it illuminates it. It exposes the absurdity, the terror, and the humanity of a condition so often misunderstood or hidden.
A story told with nuance, honesty, and shocking clarity
The show’s structure—intercutting stand‑up routines, voice notes, and moments of startling emotional candour—creates a rhythm that is both unpredictable and deeply affecting. Its “nuances, subtle nods and out‑and‑out shocking moments” (to borrow my own immediate reaction) land with force because they are grounded in lived experience. Nixon has spoken openly about her own OCD and postnatal mental health struggles, and the press release highlights how “she finally realised she had had intrusive thoughts all her life” after the birth of her first child . That authenticity radiates through every beat of the performance.
There is a moment—one of several—where the audience is confronted with the reality of infant death. It is handled with such stark honesty that the laughter that follows minutes later feels almost transgressive. Yet that is the genius of Baby Brain: it trusts its audience to hold multiple truths at once. It trusts us to sit in discomfort, to feel the contradictions, to recognise that grief and humour can coexist without diminishing each other.
“Kimberley Nixon delivers a performance so fearless and so precise that you feel every fracture and every flicker of hope”
A production destined to resonate
The creative partnership between Nixon and Nelson Nutmeg Pictures’ Tim Clague and Danny Stack is clearly built on a shared appetite for “honest storytelling and a shared taste for the darkly comic” . Their collaboration has produced a piece that feels meticulously crafted yet emotionally untamed.
Audience reactions tonight mirrored those quoted in the press release—“extraordinarily moving,” “hilarious, bonkers,” “well crafted, very clever” —but experiencing it firsthand reveals just how deeply this show will resonate with anyone who sees it. It is not simply a performance; it is an act of advocacy, empathy, and artistic courage.
Baby Brain challenges the glossy, sanitised image of motherhood that dominates social media and replaces it with something far more powerful: truth. Messy, frightening, funny, human truth.
“This is the rare kind of show that doesn’t just stay with you—it unsettles you, comforts you, and opens your eyes all at once”
