William is a cutie, a lovely little boy. However, at the polo he didn't interact with any of the other children, seemed confused as to who Zara and Autumn were, and didn't take any notice of them.
It was the same story with his grandfather. We didn't see any rough-housing or grandfatherly hugs, or hugs from uncle Harry, or embraces from George towards either of these two relatives.
The only person George seemed to be reacting to was his mother and, briefly, his father. The inanimate polo stick received more of this toddler's attention, as did his wooden train.
Just how often does George see his uncle and grandfather, let alone people like Zara and Autumn and their lovely and lively children?
It's fine for Kate to bring George to the polo to meet these relatives. However, they can't disguise the fact of his not really knowing anyone.
It was the same on the balcony at the Trooping of the Colour. Not one bit of real interaction between this little boy and his Windsor relatives with the exception of his parents. A glance maybe, from Charles, Harry hung back, the Queen took no notice of her toddler great-grandson. Nothing. Just take a look at those photos.
