Siamese twin sisters who were given a million-chance to survive, have chances to become happy, healthy 16-year-olds.
And now bright A * students Zainab and Jannat Rahman hope to pursue their dream careers at Oxbridge universities.
The girls were born as one, merged from the chest to the belly, and shared one liver.
And it took a risky pioneering operation to separate them at six weeks old – with doctors who gave them only a million to a chance of survival.
Although the surgical skills have managed to physically separate the girls, their unbreakable emotional bond has always held them together.
And it means that they have only spent ONE NIGHT.
But Zainab and Jannat have now celebrated their 16th birthday, both knowing that this could change in a few years.
Zainab strives towards Cambridge to achieve her ambition to become a pediatrician at Great Ormond Street Hospital, where their lives were saved.
Jannat is studying three languages and wants to go to Oxford. She plans to become a lawyer and live in France.
Zainab said, "Maybe it will be difficult, but I think we should be independent at some point."
Jannat adds: "People ask us:" Do you want to go well? "I think so, as we get older, we have more confidence."
But the parents who have seen their little miracles grow up, think where they are, they will never part.
Dad Luther, 42, said: "I laugh when I hear them say that, as I know, they will end up in the same place, so I'm not worried.
"Although they do their best to differ from each other, they do the same, I am convinced that this is because they were merged.
"When they were younger, they sat opposite each other in a room and they laughed at each other and laughed before they could even talk, they always had a deep connection. & # 39;
Mother Nipa (36) spoke of her pride to see the girls she once feared might not be 16 years old.
She said, "It's unreal, it feels like they were babies yesterday, they are blooming, and I'm so proud."
Zainab and Jannat were born at Homerton Hospital, East London, in 2002, weigh 6lbs together and share a liver – the only organ in the human body that can regenerate.
Zainab was the healthiest and had 60 percent of the liver while Jannat suffered a hole in her heart.
The prognosis for their survival was not good – but renowned Great Ormond Street surgeons Prof. Lewis Spitz and Edward Keily prepared for just six weeks after birth.
Luther said, "The day they took them for the operation I held them and I cried, my tears fell on Jannat's face, and she just laughed at me That smile, I say to her every day, said: & # 39; Do not worry I'll be back & # 39 ;. "
And when they came back, Jannat went on with another six operations to repair her bowels and the hole in her heart and she left with a long scar on her chest. The telling and retelling of their survival is now deep in family folklore. When the girls celebrated their 16th with a big bash, complete with DJ and 120 guests, Zainab said: "We grew up with the story of what happened to us.
"There was no day when our parents did not mention it, and it was not until we got older that we realized how complicated everything was and how happy we were."
The girls say they were five when they first remembered that they had seen photos of themselves. Jannat said: "I did not think the photo was real, it was so strange to see something like that It was strange to see that it was us At the primary school, people asked us who is older and we would say & # 39; we were merged & # 39 ;.
& # 39; But I do not think we realized what this meant until later. & # 39;
Zainab was the noisiest, more outgoing twin until the girls turned four. They were 10 before they spent their only night apart. Jannat, who was ill at the time, slept on her nan's.
As they grew up, their personalities slowly switched and now Jannat is the more active, energetic person who plays football, cricket and netball for her school.
Zainab is now the larger bookworm. Yet they have the same friends, they share clothes, complete each other's sentences and even make their homework together at the same desk. Together they prepare to take their GCSE & # 39; s in the summer and hope to sweep the board with A * degrees.
Zainab is the top of her year for mathematics. She said, "I've been interested in medicine for a while, I want to become a pediatrician and work in Great Ormond Street."
Jannat still has to check her heart, but has not experienced any adverse effects from the morbid twins. Proud father Luther can not wait to see what his girls can achieve.
"Even to this day it is clear to me that they are still here with us," he said.
"I say they do what you want, achieve what you want, I want to tell other families with sick children that they should not lose hope, there is always a chance."
