She's often spoken of the pain of losing her son, Archie, more than 21 weeks into the pregnancy.

And now - eight years on - Kym Marsh has again paid tribute to him, revealing that without him she doesn't believe her daughter would have made it either.

The Corrie actress, 40, explained in conversation with The Mirror: "We could all sit down and go, you know what, I have lost a child, I can’t move on. And I fully understand how people can feel like that. "But there is light at the end of the tunnel," she added. "You can move forward, you can be happy again." Kym also stated: "I would walk through the door and Polly would be there running round and asking what is for dinner. She doesn’t care whether I have had a bad day or not, she just wants her mum." She went on to say that she doesn't believe that Polly would have made it had it not been for Archie. Indeed, her doctors, knowing that she was high-risk, monitored her closely during that subsequent pregnancy - something which may well have saved her daughter's life. Polly was eventually born at 33 weeks - weighing in at just 4lbs and spending her early weeks in hospital. "Obviously Polly is my little miracle. She is six now and there were times when I was pregnant when I didn’t think we were going to have her, and we nearly lost her several times." Kym added: "We lost Archie and we didn’t think we were going to have Polly."

Earlier this year, Kym explained that not getting a birth-cert for Archie was devastating. She also said that the term 'late miscarriage' bothered her. ''It really annoyed me and it angered me. I had just given birth to a baby. I didn't miscarry my baby, I gave birth to him, and why is there no birth certificate?'' she asked. "The clue is in the name, 'birth certificate'. So why? Because he didn't survive? Because he wasn't 'viable'? What is that? When I'm not here anymore, no-one will know that my baby existed. "And that's the thing that upsets a lot of women, where you can't have a birth certificate,'' she furthermore told Digital Spy. Ms Marsh famously depicted a similar scenario on-screen - when her Coronation Street character, Michelle Connor, gave birth prematurely to a son, Ruairi. She has son David, 22, and a daughter, Emily, 19, as well as Polly.
