The Duke & Duchess of Sussex have sparked fresh baby fever as they referred to their first child as ‘Baby Sussex’ for the first time.

On their official Instagram page, Prince Harry and Meghan thanked everyone for their donations to charities for children and parents instead of sending them gifts.

As they count down the days until their baby’s due date, the couple said ‘On behalf of The Duke and Duchess (and Baby Sussex), we thank you so much.’

The reference to ‘Baby Sussex’ delighted royal fans on social media, with one saying  ‘Mentioning Baby Sussex is the cherry on top!’

Harry and Meghan are believed to be planning a home birth for their first child at their new home Frogmore Cottage, close to the Queen’s Windsor Castle home.
