When Rebecca Gale arrived at the Norfolk and Norwich University Hospital at 7am yesterday for the birth of her third child, the maternity ward was already buzzing with the news the Duchess of Cambridge had gone into labour.

The 33-year-old, of Beeston Regis, near Sheringham, said she had been following the progress of Kate's pregnancy as they had both suffered from bad morning sickness at around the same time.

Mrs Gale's son, Benjamin William Gale, arrived at 9.11am yesterday, weighing 8lb 13oz, following an elective caesarean – a week before his due date.

Mrs Gale yesterday said she was excited by the fact William and Kate's boy would have the same birthday as her son.

She joked that the Duchess had been hanging on for her son to arrive first and family and friends had been texting her during the day with updates on the Royal baby news.

'We were both quite excited when we found out at 7.30am that she had gone into labour. Everyone likes Kate and it would be great for Benjamin to have the same birthday as the Prince.

'I feel sorry for her going through labour in this heat, especially in London where it is hotter than here.

'It must be awful for her with everyone wanting to know what is happening. I hope everyone leaves her alone for a few days now,' she said.

The birth of Mrs Gale's first son follows the arrival of Evie, four, and Poppy, two, who were both born by caesarean section.
