A British toddler beat the odds by surviving four heart attacks when he was just 11-weeks old.
Oliver, who was born on January 16, 2007 at Queen Charlotte's Hospital, London, had medical complications since the time he was born.
The doctors at the hospital found he had an irregular heartbeat.
And one day, the child's parents, Bryan and Anna noticed that Oliver wasn't feeding and had become drowsy.
The doctors informed the couple that their child's condition was critical. Three times doctors tried to shock Oliver's heart back to a normal rhythm, without success. So he was shifted to another hospital, where he went on ECMO machine, which pumps blood around the body.
Oliver's heart had enlarged, and so he needed bypass surgery.
At the new hospital, the boy suffered a cardiac arrest and was being shocked again.
Although the underlying syndrome couldn't be cured, medics hoped that ECMO machine would keep him stabilized enough so that the condition could be treated with medication. But the solution was a short-term one.
For 18 days, the parents stayed by Oliver's bed, praying that their son's heart would be strong enough to keep him alive when they took him off the machine.
But three attempts failed, leaving his parents in despair.
On the day 18, the couple was told that their son was fine.
For the next two months, Oliver's parents kept a close eye on the heart monitor next to his bed.
But, just as things started to look better with Oliver, he suffered a terrifying setback - due to toxic poisoning from one of his medicines.
He suffered three cardiac arrests over two days.
Just as the couple strengthened themselves to bid farewell to their beloved son, the moment of Oliver's most dramatic fightback.
"He's so strong. To think someone so tiny can go through so much and survive," Mirror quoted Anna, as saying about his miracle baby.
