A toddler thought to have tonsillitis after she began rejecting food was found to have swallowed a button-sized battery that had been stuck in her throat - for four months.
Little Sofia-Grace Hill, almost two, was rushed to hospital where shocking X-rays revealed a tiny watch battery - the size of a 10p - lodged in, and burning, her oesophagus.
Surgeons performed a two-hour operation to remove the object and claimed Sofia-Grace s survival may be due to the battery being old and discharged.
