A heartbroken father has shared a post-operation picture of his son who required 28 life-saving surgeries after swallowing a tiny battery.
Ollie Lennon was only one year old when his parents noticed that he was struggling to keep down solid food, with medics initially thinking he had croup or asthma.
It was several days later that an x-ray revealed a button battery was lodged in his throat.
