Overview
- Season five began streaming on Apple TV on Wednesday, July 8, 2026, with eight episodes released weekly and new installments arriving each Wednesday.
- The new season centers on Kat, the siblings’ biological mother, re-entering their lives and creating emotional tension that particularly challenges Nikki’s sense of security as a parent.
- Producers keep the show's six-year time jump as a structural device to show the adopted children as teenagers and to allow major character growth since the apparent season-three finale.
- The season adds new cast members including Celia Imrie, Gbemisola Ikumelo and Colin Morgan while keeping Esther Smith and Rafe Spall’s widely praised chemistry at the core.
- Tonal continuity remains a priority: the show balances warm, grounded comedy with serious themes about identity, belonging and how parents and teens renegotiate roles, and it also shows the couple facing work and life changes that reshape their household.
