The move may mean that Meghan chooses not to give birth at the Lindo Wing, the exclusive maternity ward at St Mary’s Hospital in Central London where the Duchess of Cambridge had her three children, but instead use a hospital ‘closer to home’.

One option would be Frimley Park Hospital in Berkshire, which is about 15 miles from Windsor and where the Countess of Wessex had her children.

It comes amid reports Meghan and Harry are considering raising their child ‘gender neutral’ – understood to mean they will not enforce any male or female stereotypes.

According to a source, who has known the Duchess for many years and was at her wedding: ‘Meghan has been talking to some of her friends about the birth and how she and Harry plan to raise their baby.

‘She said they plan to raise their child with a fluid approach to gender and they won’t be imposing any stereotypes.’

The most likely scenario is that the couple could choose to forgo traditional blues and pinks to match the baby’s gender. They could also avoid conventional gender-biased toys such as dolls for girls and train sets for boys.

Last night a senior Kensington Palace aide refused to rule out the possibility of the baby being raised gender neutral.

The couple are understood to have chosen neutral grey and white hues for the nursery, rather than the blue or pink.

Meghan has transformed her husband in many ways: Harry has given up alcohol in solidarity with his pregnant wife, quit smoking and recently revealed he starts the day by meditating. But the Duke is still very much a traditionalist at heart. He has continued his passion for hunting and shooting despite Meghan’s love for animals.

And as a young boy, he was always running around Highgrove in military fatigues, climbing trees and playing toy soldiers with Prince William.

Meghan has also revealed she played with dolls as a child.

A spokesman for Kensington Palace last night said: ‘The Duke and Duchess are extremely excited to welcome their first child in the spring.’
