Kate and Gerry McCann have told of their hopes for their youngest children as they grow up in the shadow of Madeleine's disappearance.
Speaking in an interview to mark the sixth anniversary of their daughter's abduction in Portugal, the McCanns, of Rothley, said eight-year-old twins Sean and Amelie would be celebrating Madeleine's 10th birthday with them on May 12.
Kate, 45, said the twins were coping well.
She said: "They've grown up knowing Madeleine is missing.
"She is their big sister, we're trying to find her and she should be back home with us.
"Any question they have put to us we have answered and that's all we can carry on doing. Communication and information makes anybody feel more comfortable.
"At the moment, they are doing brilliantly.
"They have coped amazingly well and in many ways they are no different to any other eight-year-old children.
"As they get older and they wander on the internet and other things, there will be more questions, but going by how things have panned out so far, I think we will be all right, I think they'll handle it well."
Madeleine was nearly four when she disappeared from her family's holiday apartment in Praia da Luz, Algarve, on May 3, 2007.
Kate said Madeleine's birthday was a more difficult time than the anniversary of her disappearance.
"Her birthday is difficult," she said.
"We both find that more difficult really because it's her special day and we should be there celebrating it and we still do.
"We still celebrate her anyway and the same will happen this year – we have a little birthday tea and a cake."
The Metropolitan Police are reviewing the evidence and carrying out their own investigation, which the couple said gave them new hope.
During the interview, Gerry, 44, said the couple had found a "new normality" over the past few years as they came to terms with the absence of their oldest child.
He said: "In many ways, things haven't changed and you could argue that, with the Met review two years in, we are in a better place because so much more information has been collated and lots of pieces of the jigsaw have been filled.
"We are still in the same situation and for us we have to keep going until we find Madeleine and those responsible."
"The Met are absolutely determined to see the job through.
"They feel like they are getting their teeth into the job."
The couple will mark the anniversary with a service in Rothley tonight.
