Maternity staff at the Queen Elizabeth Hospital in King's Lynn normally expect to deliver an average of six babies a day.

But on the day the nation waited for news on the Duke and Duchess's new arrival, they helped deliver 11 new bundles of joy.

Another tot decided not to wait as his parents drove to the hospital and was born in their car on the way instead.

Watching the images of William and Kate presenting their newborn son to the world's media on Monday evening were Newmarket couple Zhi Wei Zheng and Darlene Suttle and their 18-month-old daughter Zhia.

Sitting in their caravan at Manor Park in Hunstanton at about 9.30pm, Miss Suttle suddenly began to get the feeling that their second child was not about to wait until his due date of May 13.

A fellow caravan owner agreed to drive them to QEH. But a few miles down the road, near Snettisham, Miss Suttle felt the need to push and her 7lb 1oz son into her own arms, sitting alongside her partner in the back of the moving car.

She said: 'I was trying to be as quiet as possible because I didn't want to worry the driver.'

When the car arrived at QEH, Mr Zheng leapt out. He said: 'I ran into A&E and said: 'My wife's had a baby in the car!'

Seven minutes after the Duchess gave birth at 11.01am, Swaffham mum Louise Lamb had her second child Rosie June, weighing 7lb.

Miss Lamb had an elective Caesarean and arrived at 8am.

'My sister texted me at 10am to say that I was in competition!' said Miss Lamb. 'I didn't find out until afterwards that Kate had beaten me.'

Miss Lamb is a big fan of the Royal family, particularly Kate, who she has seen shopping in Waitrose in Swaffham.

One mum who beat Kate was Julija Zeimyte, from King's Lynn, whose third child Sofia arrived at 1.47am, weighing 6lbs 1oz.

'I was tired but she [Kate] looked amazing,' she said. 'No way would I have wanted the attention she got.'

Lesley Deacon, head of midwifery at The Queen Elizabeth Hospital King's Lynn NHS Foundation Trust, said: 'We're delighted to have had so many babies safely delivered here on such a special day for the Royal family.'
