The new nanny was seen pushing Prince George in a stroller in Hyde Park, accompanied by a security officer, on March 4.
The nanny is reportedly in her 30s, hails from Spain but has resided in the UK for more than 20 years, and, says a source for Hello! Magazine (the first to report the news), she "lives for her job." She was hired around a month ago, and Kate's mom, Carole Middleton, has been showing her what to do.
Kate and William are due overseas for a royal tour in New Zealand and Australia next month; and Prince George will be joining them—his first big trip! The new nanny is scheduled to come along and tend to Prince George while Mom and Dad go to their various royal engagements.
The royal baby may join them on a few of these engagements, however. "One or two engagements across the three weeks have been identified as times when the Duke and Duchess might take Prince George along, too," William's private secretary, Miguel Head, told the press (according to Hello!).
"I'm sure you will appreciate that the couple will have to make a final decision on those moments much closer to the time," he added. "The Duke and Duchess are content enough to know that he will be with them in the two countries."
