The NHS have written to the parents of a 3st 5lb (21.3kg) five-year-old boy from Nottinghamshire claiming he is overweight.
The letter was based on the little boy's body bass index which was calculated after his height (3ft 7in or 1.1m) and weight were checked during a school medical earlier in the year.
The child's furious mother has spoken out again NHS Nottinghamshire, saying her son walked to and from school, played football, and had a balanced diet.
The letter was sent out by the school's health visitors before the children broke up for the summer.
His angry mum told the BBC: 'I was absolutely furious because our son is not overweight at all. He's a very healthy child who at a very young age has now been marked as overweight.'
Awful - have you received one of these letters?
