From Pontypridd to Edinburgh: five-star one-woman dark comedy plays six UK cities from 30 May Welsh actress Kimberley Nixon (Fresh Meat, Under Salt Marsh) takes Baby Brain on a six-city UK tour this summer, opening in her hometown of Pontypridd on 30 May and closing with a ten-night run at the Edinburgh Fringe in August. Stops in between include the Rik Mayall Comedy Festival in Droitwich, Lighthouse Poole, Manchester Fringe and Camden Fringe.
Baby Brain is a darkly comic one-woman show about a new mother, Cass, in the grip of postpartum psychosis. Stand-up routines, voice notes and a fourth-wall-breaking format pull audiences inside Cass's head as she fights to tell what's real from what isn't. The 55-minute show was co-written by Nixon with writer-directors Tim Clague and Danny Stack of Nelson Nutmeg Pictures.
The world premiere at Porter's, Cardiff in March 2026 sold out, earned a five-star review, and triggered an additional performance to meet demand. The show's Kickstarter tour fund hit 150% of its target.

Baby Brain is endorsed by Action on Postpartum Psychosis (APP), the UK's leading charity for women and families affected by the condition. Postpartum psychosis affects approximately 1-2 in 1,000 new mothers, often within the first weeks after birth, and remains one of the least-understood maternal mental health emergencies. Nixon, who has spoken publicly about her own experience of severe perinatal OCD and built a 300,000-strong Instagram community around maternal mental health, draws on that broader advocacy in shaping the show.
Kimberley Nixon said: "I'm taking a one-woman show about postpartum psychosis from a community performance in Pontypridd to the Edinburgh Fringe, with a few stops in between. That sounds about right for a play about losing your mind. I genuinely cannot wait."
Danny Stack, co-writer and director, said: "We sold out Cardiff, hit 150% on Kickstarter, and at every preview, people stayed behind to talk to Kim. Postpartum psychosis is a deeply unsettling condition, no laughing matter at all, but we use comedy to really understand what a new mum is going through. APP's endorsement means everything. The people who know this condition better than anyone are telling us we got it right."
