“We want the babies to just stop crying and we’re going to leave them in the other room but you guys just want to be held and picked up and keep whining.”
It comes as Harry said he wants his father and brother back during an ITV interview due to be released this Sunday, two days before his memoir is published.
But in the separate 60 Minutes interview with CBS News, set to air the same day, Harry also criticises Buckingham Palace over an alleged failure to defend him and his wife, the Duchess of Sussex, before they stepped down as senior royals.
The Duke also reveals to the US broadcaster that he would not return to the institution as a full-time royal.
In a clip, released on Monday, Harry tells Cooper he felt there was a lack of protection for him and Meghan against stories in the media, commenting: “There comes a point when silence is betrayal.”
