George greets another baby during a play date at the Government House in Wellington.
Appearing at his first official royal engagement, Prince George joins in a play date with other babies in Wellington. Here, he's seen playing with a toy during the Plunket nurse and parents group event at the Government House.
All the 10 babies attending the play date were born within a few weeks of George. He was the biggest: "Quite a bruiser" said one onlooker.
There was at least one incident of theft: Amelia Howe was playing with a plastic block. George grabbed it, Amelia screamed and the Howes apologized to the duchess. They later explained that Amelia had hurt herself by biting down too hard on the toy. "This one was chewing on a toy and she's teething so she bit it and it obviously hurt her. She dropped it and the toy got flogged and that was the end of it," her father said.

George, at just 8 months old, made his first visit to New Zealand and Australia as a baby -- just like his father.
