Sources at Kensington Palace are confirming that Prince William has returned to work as a search and rescue helicopter pilot on remote Anglesey, while Kate is staying on at her mum's in Berkshire, closer to London.
So far the new family have spent just one night at their London residence, Kensington Palace.
William will be back flying helicopters on his regular shifts in Wales rom today. He is ilkely, however, to have plenty of opportunity to spend time with his family because of the intensive nature of the work which sees pilots spend several days on call and then having several days off duty.
William is the first member of the royal family to have taken paternity leave.
