A mother from Winchester has been sharing her story of life with her young quadruplets to mark their first birthday.
The birthday coincides with the 70th anniversary of the NHS. The first test tube baby was born forty years ago, and since then millions of babies - including the quadruplets and their older sister, have been born to parents who otherwise would not have been able to have children.
The odds of having twins is high with IVF, and doctors limit the number of embryos they transfer. However it is not always possible to control nature.
The three identical brothers - Roman, Austin and Arlo, along with their sister Raeya were born when their parents were trying for a second child.
The children's mother, Selina Torbett, has returned to her job as a nurse at a stroke unit in Winchester. The family want to thank the NHS staff who looked after the quadruplets when they were born 11 weeks premature with underdeveloped lungs. The NHS has been an important part of their lives, with teams at hospitals in Southampton, Salisbury, Winchester and Oxford contributing to their care.
The quadruplets were treated to a photo shoot with photographer Julie Davis - and some cake for their first birthday. Watch Kerry Swain's report below:
