Atiya Anjum-Wilkinson is back with her mother in Greater Manchester three years after being abducted by her father and taken to Pakistan.
The six-year-old flew into Manchester Airport on Friday night on a Pakistan International Airlines flight from Islamabad accompanied by her uncle.
Speaking after seeing her daughter for the first time since 2009, Gemma Wilkinson said she was "absolutely overwhelmed".
She said: "We've literally gone from not knowing where Atiya is, to then finding out that we do know where Atiya is, to receiving pictures of Atiya and how she looks now, and then to Atiya's coming home and now she's here.
"It's been an absolute whirlwind. It's more than I could ever imagine or hope for."
Sky Correspondent Frazer Maude, in Manchester, said: "It is going to be a very difficult period of readjustment that could take some time.
"She has spent three years living in Pakistan with her extended family, we believe, and she will be returning here to try and relearn a Western way of life.
"These must be very difficult times for her mother as well, the uncertainty as to what reaction she is going to get from her daughter, whether her daughter will even speak the same language when she arrives."
MEP Sajjad Karim, who contacted Pakistan authorities to try and track down Atiya, told Sky News he wished he had known about the case earlier.
He said: "There is nothing that I have done now, that I couldn't have done three and a half years ago."
Mr Karim added that Atiya was located on Christmas Eve and authorities were able to show up-to-date pictures of her to Ms Wilkinson on Christmas Day.
No money changed hands in getting her back, he said.
Atiya vanished in November 2009 after going to stay with her father, Razwan Ali Anjum.
The former insurance salesman said he was taking her to Southport.
Instead he took her to Lahore, Pakistan, and told Ms Wilkinson she was "never going to see Atiya again", courts have heard.
Anjum is serving a prison sentence in Britain for refusing to reveal his daughter's whereabouts despite a court order.
Ms Wilkinson's "on-off" relationship with Anjum ended in 2008.
Anjum was handed a fourth consecutive jail term by a High Court judge in April after he refused to say where his daughter was.
Mr Justice Moor imposed a 12-month sentence after he found him in contempt of a High Court order instructing him to disclose Atiya's whereabouts.
He said Anjum, in his late 20s, would not be eligible for release until he had served at least six months. He had previously been given one two-year and two 12-month sentences.
