The Duchess of Cambridge, 40, arrived in Copenhagen on Tuesday for a two-day visit that will highlight her Early Year Foundation and honor Queen Elizabeth's Platinum Jubilee year. Upon her arrival, she was greeted by Emma Hopkins, the British ambassador to Denmark. It is the second time Kate has visited Denmark — the first time was in 2011, shortly after her royal wedding to Prince William. Kate's first stop was to the University of Copenhagen to learn from world-leading researchers running the Copenhagen Infant Mental Health Project (CIMHP),which aims to promote the mental well-being of and relationships between infants and their parents.

"One of the things that's really impressed me, because I hear it time and time again, is how the science is being translated here into practice. So all the amazing research that's out there from neuroscientists and psychologists are actually being translated into tangible language that parents are using on a day-to-day basis," she said. The Duchess of Cambridge's last major overseas tour was alongside her husband Prince William in 2019 during their trip to Pakistan. Her last solo tour was in 2017 when she traveled to Luxembourg. William recently returned from his own solo overseas tour to Dubai.
