(CNN) -- Britain's Prince George is now safely back home and tucked-up behind palace walls after taking his first tentative steps into a lifetime of public duties. In the end, he only officially appeared twice during the Duke and Duchess of Cambridge's tour of New Zealand and Australia. First, at a play date in Wellington, then at Taronga Zoo in Sydney, but we also caught glimpses of him getting on and off planes. So what did we learn about this little monarch-in-waiting? Well for a start, he isn't little. The other babies invited to the play date were all born within a few weeks of George and he was by far the biggest, and he's quick. "Very strong, very mobile, very happy, very active," said Peter Howe, who was one of the parents invited to the event. Another described the prince as "intrepid."

This is exactly the age when I remember my babies starting to transform and I could see that in @placeholder over the course of the three-week tour as well.
