For the children and parents in this episode, tough life lessons have an added dimension, but they're determined to push on through, in the face of uncertainty. Four-year-old Rosie has leukaemia. Her dad Chris has put normal life on hold to become her full-time carer as he and her mum Jenny do everything they can to help Rosie in her fight to get better and start walking again. Fifteen-year-old Joseph was involved in a serious road traffic collision six years ago. He still struggles with serious hip pain and with GCSEs looming his mum is determined to find out the cause and get him off of the painkillers in time for his exams.
