Kate McCann has revealed how her twins want to help in the search for missing daughter Madeleine.
Speaking on Wednesday morning she told ITV's Lorraine: "Sean said to me, and this is going back about 18 months now, he said, 'Shall I come and work for you and find Madeleine when we get older?'."
In a series of media interviews on Wednesday, the McCanns told how they believe their daughter, who has been missing for five years, is still alive.
Kate and Gerry McCann both spoke of their renewed hope that their daughter Madeleine will be found.
Kate McCann said an ongoing review of the case by Scotland Yard and the release of a new age-progression picture of Madeleine had left them feeling "probably as positive" as they had been for a long time.
"We are realistic. We don't know what has happened but we know there is a very good chance that she could be alive - there is no evidence to the contrary," she said.

The Birth of Mongoose Lemur Twins Last month, Busch Gardens witnessed an uncommon event: the birth of mongoose lemur twins. The two babies were born to 17-year-old mother Rosalita and 18-year-old father Guillermo. Rosalita's first baby - a male named Duggan - was also born at Busch Gardens and moved to another zoo for breeding. Busch Gardens zoo staff aren't yet sure if the new babies are male or female. All baby mongoose lemurs look the same at birth, but at around six to eight months of age, males start to change colour and develop their red "beard" and cheeks. Females have a darker face and white beard. USA - May 2012 MANDATORY CREDIT: Matt Marriott/Busch Gardens Tampa Bay/WENN Supplied by WENN.com
