Harper Platt is the newborn daughter of
David (
Jack P. Shepherd) and
Shona Platt (
Julia Goulding). She was born on 7 January 2026 via
caesarean section at 28 weeks. In September 2025, Shona reveals to her husband David that she is pregnant, after David finds a positive
pregnancy test in the bin and assumes that it belongs to his teenage daughter
Lily Platt (Grace Ashcroft-Gardner). During their first scan in November 2025, Shona and David are informed that there is a large mass on the baby's neck, which may be cancerous. A special episode which examines both David's and Shona's perspectives of the pregnancy was broadcast on 12 November 2025, where it is confirmed that their baby has a
cervical teratoma, and Shona will need to undergo an
EXIT procedure to ensure her and the baby's best chances of survival. David and Shona are also offered the option of a
termination, which David encourages Shona to consider, leading to tensions within their marriage when Shona refuses. In January 2026, David and Shona are involved in a multi-vehicle accident during the special hour-long
Corriedale episode, where
Coronation Street and fellow
ITV1 soap
Emmerdale crossover. Shortly after the crash, Shona goes into labour, and David suffers an
epileptic seizure. After being transferred from Hotten to Weatherfield, Shona gives birth via caesarean section, and she and David name their baby Harper, after the surgeon who delivered her,
Vincent Harper (
John Hollingworth). Jodie is later revealed to be Shona's half-sister. ==Lee==
