Royal Baby: Will baby be born on Kate and William’s anniversary or Queen’s birthday?

Kate Middleton and Prince William are expecting their third child, and the due date is looming.

As the royal baby will be born soon, punters are wondering which days have the best odds, and they are monumental days for the British Royal Family.

William, 35, and Kate, 36, already have two children, Prince George, four, and Princess Charlotte, two. When will their third bundle of joy arrive?

When is the royal baby due?

According to bookies the child could arrive on Kate Middleton and Prince William’s wedding anniversary.

However, the Queen’s birthday is also a contender, according to Ladbrokes.

The baby could arrive on Her Majesty's birthday according to the latest odds from Ladbrokes.

As The Duchess of Cambridge enters the final few weeks of her third pregnancy, the bookies have opened up betting on when the latest addition will enter the world, and 21 April - The Queen's birthday - is the early favourite at 10/1.

The odds on offer for St George's Day - 23 April - is 12/1.

Punters reckon Prince George and Princess Charlotte are going to be joined by a little sister at 4/5, or there's even money on offer for a little brother.

Jessica Bridge of Ladbrokes said: "With Kate's due date only weeks away the betting suggests the latest addition to the Royal Family could share a birthday with his or her Great-Grandmother."

According to experts, women often do not give birth on their due date. There is a very small chance Kate will have the child on the day doctors have predicted.

Kate Middleton’s due date has not been disclosed to the public, however the Duke and Duchess of Cambridge are no doubt aware of when their third child expected to arrive. 

“It’s worth remembering that only 5 per cent of babies are actually born on this estimated date of birth,” hospital midwife Sally Goodwin told Emma’s Diary.

“The last few weeks of your pregnancy are both exciting and tiring,” she continued. “It is also perfectly normal for women to focus on their due date at this stage of pregnancy too.

“It’s understandable to feel disappointed if baby has not arrived by this date," she added.

What is the royal baby’s sex? 

Prince William and Kate do not known whether they will be having a girl or a boy, according to reports.

However royal parents don’t have a choice, and tradition dictates they do not know the sex of their child until it is born.

A source told E! News: “William and Kate don't know the sex of the baby, so they're rather looking forward to finding out.
