:: The Lindo Wing

This is the exclusive private unit at St Mary's Hospital in Paddington where Kate also gave birth to Prince George back in July 2013.

A suite of two rooms now costs £6,570 for a one-night stay with normal delivery plus consultant fees of around £6,000.

But because this is her second child Kate is eligible for a 10% discount.

The Lindo Wing prides itself on offering privacy to its clients, which is, of course, essential for the royal couple.

Its website says: "Discretion is key to our service, and we will ensure that you have the space, security and privacy you need to enjoy these precious early moments as a family."

The rooms come with all the added extras you'd expect from a good hotel room, with wifi, TV, a radio, a safe, a bedside phone and a fridge.

As well as freshly prepared meals, parents are also offered a "comprehensive wine list should you wish to enjoy a glass of champagne and toast your baby's arrival".

But siblings of the newborn are not allowed to stay over, so if Prince George does visit he will have to go home with the nanny or his grandparents.

The Lindo Wing has a long-standing connection with royal births, with William and Harry both born there, along with Peter and Zara Phillips.

:: The medical team

By Kate's side were doctors and nurses she already knows well from her time giving birth to Prince George.

They were led by Guy Thorpe Beeston, a consultant obstetrician and gynaecologist at the Chelsea and Westminster Hospital and a member of the high-risk pregnancy team.

He is also surgeon-gynaecologist to the Royal Household.

Alan Farthing, a consultant gynaecological surgeon, also supported the Duchess. He assisted Sir Marcus Setchell, who led the team for Prince George's birth.

When Sir Marcus retired Mr Farthing took over his role as surgeon-gynaecologist to the Queen.

Dr Sunit Godambe, consultant neonatologist at Imperial College NHS Trust, and Professor Huw Thomas, physician to The Queen and head of the Medical Household were also present.

:: Second labour was shorter

Kate's experience proves what many midwives will tell you - a second child can appear much faster than the first.

The Duchess went into hospital at around 6am on the day Prince George was born and he arrived 10.5 hours later at 4.24pm, weighing 8lb 6oz.

This time around, Kate went into hospital at the same time but her daughter was born at 8.34am, weighing 8lb 3oz.

Mervi Jokinen, of the Royal College of Midwives and president of the European Midwives Association, said: "Individual labours are different, but we definitely see shorter labours second time around.

"Your body seems to be programmed. The hormones kick in quicker and progression is faster.

"The pushing stage can also be quicker because it's your second one.

"Muscles have been stretched so you have less resistance and you have the ability to push the baby past the birth canal."

Kate had a straightforward, natural birth with George with no complications.
