A spokesman for the Sussexes said: "Due to the logistical planning for the travelling press to cover visits and engagements by The Royal Family, we have taken the decision to postpone The Duke of Sussex's scheduled visit to Amsterdam on Wednesday 8th May 2019.
"The Duke is currently scheduled to travel to The Hague on Thursday 9th May for the launch of the Invictus Games The Hague 2020 as planned."
It came as pink blankets in a Bentley driving near Prince Harry and Meghan's home in Windsor sparked excited panic that a royal baby might be here.
A witness said he spotted a pink blanket in the posh car, which was being escorted by a police motorcade.
Tamoor Ali told The Sun: "We saw a vehicle that had pink paraphernalia at the back of the windscreen go past — it was going very slowly over speed bumps.
"It seemed to me some kind of blanket of some sort.
"It seemed like someone was in there who couldn't handle speed bumps — a baby."
But Buckingham Palace has poured cold water on the excitement, saying the car and the pink blanket were not related to the Duchess of Sussex.
The sharp eyed Ali was on to something though, with sources telling the Mail Online that the car may have been carrying the Queen.
Her Majesty was due to attend service for the Royal Victorian Order at St George's Chapel in Windsor today.
The world is in the grip of baby fever, with royal watchers desperate to find out more about the birth of the Meghan and Harry's first child.
The royal couple plan to keep the birth of the child private so they have time to bond, unlike the traditional photographs on the steps of the Lindo Wing at St Mary's Hospital London.
Meghan's mother Doria Ragland was believed to be staying with her in her home of Frogmore Cottage in Windsor.
But her estranged father Thomas Markle has been spotted in Mexico getting takeaway.
He was notably absent from his daughter's wedding last year after he was caught selling information to the paparazzi shortly before the big day.
