The royal baby and mom Kate have joined Prince William at a four-bedroom farmhouse looking out over the sea in Anglesey, in north Wales, which the couple has called home for about three years.
The littlest royal is believed to have been driven the 270 miles from the Middleton family home in Bucklebury, west of London, earlier this week.
He had stayed about three weeks at his grandparents' home where Kate's mother Carole has been helping in the early weeks. Carole also made the trip.
On Wednesday, William thanked locals saying they'd never known anywhere as "beautiful and welcoming as Anglesey."
Residents are hoping that the couple will venture out. "I would love to see them – and to even catch a glimpse of them with a pram would be breathtaking," community worker Jean Owen says.
