A woman is taking legal action against a health trust in a case of alleged medical negligence.
According to Geraldine Hargrove, errors were made by staff at the Royal Gwent Hospital during the delivery of her son Cayden Sweeting, the South Wales Argus reports.
The 23-year-old suggests that her fears over the likely need for a Caesarean section due to her family's medical history were ignored.
In May 2005, she went into induced labour but Cayden got stuck and his umbilical cord was wrapped around his neck.
Ms Hargrove said: "They had to cut me, but the injection hadn't kicked in."
She added: "This was a mother's worst nightmare."
Shortly after he was born, the baby was diagnosed with Erb's Palsy in his right arm, which means the nerves in the limb are damaged.
Ms Hargrove is seeking compensation and an apology from the Aneurin Bevan Health Board - which provides medical services to a population of around 600,000.
