Instead, royal fans will get to see the happy couple with their new baby soon after the birth. Within a few days after welcoming their first child, Meghan and Harry will take part in a photo op with their new son or daughter on the grounds of Windsor Castle. Samir Hussein/WireImage Harry’s upcoming trip to the Netherlands next week has provided a clue as to when the royal baby could arrive. The prince is scheduled to visit the Netherlands on Wednesday, May 8, and Thursday, May 9 – just one week from now, which likely means that the royal couple will welcome Baby Sussex within the next few days. In the meantime, the couple is awaiting the birth of their baby from their newly-renovated home, Frogmore Cottage, which is just a five-minute walk from the Queen’s residence, Windsor Castle. Meghan’s mom, Doria Ragland, arrived at Frogmore before the Easter holiday — ahead of her first grandchild’s arrival.
