With just two months to go until the due date of the Duke and Duchess of Cambridge's baby, it was the hot topic on the Princes visit to the Help for Heroes' recovery centre at Tedworth House in Wiltshire.
William spent time bonding with patients at the recovery centre and chat quickly turned to the birth of his first child.
Dad, Corporal Josh Boggi quizzed William about the arrival, asking if he was looking forward to it, to which the Prince gushed: "very much so."
After making a speech applauding the work of Help For Heroes and his own sentiments for the charity, William returned to the topic of his child, joking: "“All the mothers have been looking at me, ‘just you wait, just you wait. Long sleepless nights'"
