'I went to see him in hospital one day to find that he'd pulled his ventilator out and his life support had switched off,' explained new mum, Danielle.
'His breathing was really heavy and there was no oxygen going to his brain and it could've caused brain damage. His skin was also discoloured and he was put back on the life support. It was the most terrifying moment of my life and I just sobbed my heart out.'
The little lad is now home with Danielle, footballer dad Jamie O'Hara and the couple's older son, Archie, one, but Danielle says the family are taking things slowly. She said Harry will develop normally but 'it'll take him longer'.
'He's on medication and vitamins every day so we just have to take each day as it comes. He has to go for a brain scan to see if there has been any lasting damage.'
