As health experts warn that nearly a quarter of youngsters aged four and five are obese, the Government's health chiefs are saying that under fives should be going swimming regularly and doing gymnastic exercise, as well as walking for at least 15 minutes every day.
The exercise guidelines will be officially issued this week in an attempt to stop obesity levels spiralling out of control.
Government medical officer Sally Davies said: "There is considerable evidence that letting children crawl, play or roll around on the floor is essential during early years.
"Play that allows under-fives to move about is critical and three hours a day is essential.
"I think there are parents who are not aware how important it is for their children to be physically active for a minimum of three hours."

Does your toddler get this much exercise already, or do you think it is totally over the top?
