While his older siblings were busykicking around a soccer balland showing off some dance moves, Louis kept mom Kate running after him as he explored the area.

Before the polo game started, Louis was “scampering out and dashing out to the edge of the polo field, and she was running out after him and picking him up, and eventually she sat down with him at the wooden border and pointed out the horses,” according to another observer. “She took him over to the polo ponies at the polo lines and chatted to the grooms with him.”

The observer adds, “He is a funny little chap. He looked very pleased with himself.”

“He had his tongue out and was waving his little hands around,” the observer adds. “He is a real character.”
