The families of two girls switched at birth are suing for millions.

The French families of two girls who were  switched at birth have appeared in court, suing doctors and  the clinic involved  the case.

For years, two French couples had doubts over  whether their daughters were really theirs and a DNA  test eventually confirmed their worst fears, revealing the girls were switched at birth.

The families of the girls now aged 20 were in court in  the south-eastern city of Grasse, suing for more than $US15 million in damages.

The story began in July 1994, when Sophie Serrano gave birth to Manon at a clinic in the French Riviera resort of Cannes, near Grasse.

The baby suffered from jaundice and doctors put her in an incubator equipped with lights to treat the problem along with another affected newborn girl.

A nurse then unwittingly switched them, and while both mothers immediately expressed doubt about the babies, pointing to their different hair lengths, they were sent home anyway.

Ten years later, troubled by the fact his daughter bore no resemblance to him with her darker skin, Manon’s father did a paternity test that revealed he was not her biological parent.

Sophie Serrano then discovered she was not Manon’s mother either, prompting a probe to try and find the other family who had been handed their biological daughter.

The investigation revealed that at the time of the births in 1994, three newborns suffered from jaundice – the two girls and a boy – and the clinic only had two incubators with the special lights.

The girls were therefore put together in one incubator, according to the lawyer of one of the obstetricians being sued.

Another obstetrician, two paediatricians, the clinic and an auxiliary nurse are also being sued.

The two sets of parents eventually met their biological daughters for the first time when they were both 10 years old, but did not ask that they be switched back.

Ten years later, both families are suing for a total of more than $US15 million.

Both families involved in the case attended Tuesday’s closed-doors court hearing but the second family opted to remain anonymous.
