The Duke and Duchess of Cambridge arrived Wednesday in Germany for the second half of a whirlwind goodwill tour through Europe.
And just like their landing two days earlier in Poland, the couple’s young children stole the show.

A sleepy Prince George, who turns 4 this weekend, didn't appear to be in the mood to live up to his royal duties as he got off the plane and met with British dignitaries.
He repeatedly rubbed his eyes with one hand while staying closely by the side of his dad with his other tightly-gripped hand.
His 2-year-old sister, Princess Charlotte, meanwhile, charmed those around her by giving her first official royal handshake to a British diplomat.
She also appeared to enjoy a small bouquet of flowers she was given, a miniature version of one her mother received.
The entire family arrived in Berlin on a private plane that departed earlier Wednesday from Warsaw. Their visit to Germany is the second leg of their goodwill visit as the United Kingdom negotiates its extrication from the European Union as part of last year's Brexit vote.
Following their landing, Prince William and his wife, Duchess Kate, received an official welcome during a meeting over lunch with German Chancellor Angela Merkel. They then paid a visit Berlin’s iconic Brandenburg Gate, an 18th century monument representing peace and European unity.
The royal couple also toured the city’s Holocaust museum and memorial, an installation containing 2,711 concrete blocks arranged in rows to depict a graveyard. It was their second visit during their European trip to honor those killed in the World War II tragedy. A day earlier in Poland, the duke and duchess tourd the Stutthof concentration camp and met with Holocaust survivors.
After the memorial, William and Kate later paid a visit a charity that provides care and support to homeless and other disadvantaged children.
They couple on Thursday will head to the harbor city of Hamburg, where they will visit a concert hall and an Airbus factory before returning home to Britain.
George and Charlotte were not expected to attend any of the public events, meaning that the young prince will be able to catch up on his sleep.
William and Kate's trip is being taken at the request of their Foreign and Commonwealth Office as part of a diplomacy tour.
The trip marks the third royal tour for Prince George and the second for Princess Charlotte, who made her worldwide debut in Canada last September.
On Tuesday, Prince William and Duchess Kate started the day touring some of Poland's historical sites, including the Stutthof concentration camp, and meeting with survivors.
