A mum has issued a stark warning to other parents after her four-year-old son was left with "painful stinging" all over his face and mouth just 30 minutes after picking up a caterpillar.
Caroline Gel, 43, said her son Oliver had been learning about caterpillars at school when he found one on a tree and decided to pick it up while playing outside last week.
Within minutes the youngster from Steventon, Oxfordshire, was complaining of a stinging sensation across his face and woke up covered in hives the following day.
