Abby, 16, is mum to Riley, seven months. She fell pregnant at the age of 15 but things didn't go according to plan. Abby, boyfriend Jake and her mum Lara were told there was an 80 per cent chance Abby's child would be severely disabled and would never walk or talk. As the doctors predicted, Riley wasn't breathing when he was born and he was rushed to intensive care. Tests found a cyst and enlarged cavities in his brain which could be life threatening. But a week later he was out of hospital.Now juggling motherhood with studying for 13 GCSEs, Abby hasn't missed a day of school since having Riley. She's determined to get her qualifications and provide a good future for her son. Abby's also desperate to find out exactly what's wrong with Riley; he has clubbed feet, webbed hands and he can't smile or suck properly. He's undergoing numerous tests but Abby still doesn't know yet if his condition is life threatening. She's looked online and thinks she might have found out the condition Riley is suffering from, but will doctors be able to give her a final diagnosis?
