Mothers and their young children are being targeted by three Solihull play centres in a campaign to fight obesity this week.
More than 300 youngsters and their parents are taking part in the national Eat Fit, Keep Fit campaign, which will see sugary snacks replaced by fresh fruit.
Leaflets, containing healthy eating tips and recipes, are available from Tumble Tots centres in Solihull, Shirley and Bentley Heath, which cater for children aged six months to seven years.
The scheme, backed by Olympic gold medallist Sally Gunnell, has been launched to tackle the rise in childhood obesity.
The Health Survey for England 2002 revealed that if the increase in children's weight continued to increase, more than 50 per cent of British children would be classed as obese by 2020.
If not tackled effectively, this could lead to a rise in heart disease, diabetes and other weight-associated problems.
Jane Thompson, spokes-woman for the Solihull centre, said: "Living a healthy lifestyle means not just being active but also eating the right food.
"It is important that the whole healthy living lifestyle is introduced from a young age if we want to build a healthier nation."
