In a report entitled "First Steps Research", nutritionists have worked out that the daily energy expended by an average toddler is the equivalent to the energy an adult would expend during 83 rounds in a boxing ring.
(In the same research the equivalent energy would be expended if an adult ran 30 miles, played 3 football matches, cycled 82 miles at 12-14mph, climbed 2,980 metres, or rowed for 6 hours.
I doubt any parent will be surprised at this.)
