The families of two babies who spent the first 10 years of their lives  with the wrong mothers after they were mistakenly switched at birth are suing the French maternity clinic responsible for nearly £10million. The blunder occurred 20 years ago when Sophie Serrano - now 38 - and another unnamed mother gave birth to daughters at a clinic in the French Riviera resort of Cannes, near Grasse. Mrs Serrano's baby girl Manon suffered from jaundice and doctors put her in an incubator equipped with lights to treat the problem along with another affected newborn girl. Scroll down for video . Sophie Serrano outside court with her non-biological daughter Manon who was mistakenly given to her at birth after a mix-up at a French maternity clinic 20 years ago. She and another unnamed mother who gave birth to Manon and was handed Mrs Serrano's biological daughter in the blunder are suing the clinic for £10m . An auxiliary nurse unwittingly switched them, and although 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. When they were located, it transpired that the daughters had grown up just 18 miles apart. The other family involved in the case also attended Tuesday's closed-doors hearing, but opted to remain anonymous. Emotional: Manon Serrano wipes away tears as she speaks to media outside court after the damages hearing . 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. 'If it happened to us, it may have happened to others,' Sophie Serrano said after the hearing, holding the hand of her non-biological daughter Manon. 'There should be exemplary sentences.... we really hope to get this recognition, so as to free us from all this guilt about not having been able to protect your kid, not having insisted when we saw there was a problem.' Manon Serrano (right) and her mother Sophie Serrano embrace a relative as they leave Grasse courthouse . For her part, Manon said she was shocked over accusations levelled in court blaming the mothers for not having recognised their children. 'She protested, she found herself in front of a qualified nurse, she was very young, she had just had a child, so putting the blame on her is absurd, I find that inhuman,' she said. The two sets of parents met their biological daughters for the first time when they were both 10 years old, but did not ask that they be switched back. 'It was a pretty disturbing moment, very bizarre,' said Manon. 'You find yourself in front of a woman who is biologically your mother but who is a stranger.' The two families have distanced themselves from each other since the meeting 10 years ago. It's too difficult, so we each went our separate ways as it's so distressing, it was the only way to find some stability again,' said Sophie Serrano. The court will rule on the case on February 10. The clinic has admitted fault - blaming what happened on the nursing auxiliary whom it claims suffered from alcoholism - but has insisted it will not pay any damages.
