Finally Aiden was born on July 16, 2012, at just 24 weeks and three days.
Under UK guidelines, 24 weeks into pregnancy is the legal abortion limit and between 23 and 24 weeks, the decision to provide support to a premature baby is down to clinicians.
If Aiden had been born just a few days earlier, doctors would not have attempted to save him and his birth would have been classed as a miscarriage.
Sean told Daily Mail that Aiden was rushed for neonatal care at Middlesbrough's James Cook University Hospital immediately after birth and spent 15 weeks there before being discharged.
But he was back within days due to a chest infection.
