Nurseries and playgroups across the UK raised £588,376 for Barnardo’s, the UK’s oldest and largest children’s charity, during last summer’s animal-themed Big Toddle. Children dressed up as animals such as tigers and giraffes and took part in a half-mile walk to raise money.

Nurseries and parents are now signing up to take part in this year’s Big Toddle which has the theme of ‘colours’. One of the biggest events in the UK will be at Dudley Zoological Gardens on Tuesday and Wednesday June 13 and 14, with free admission for participants aged up to five years old.

The gates open at 10am with the walk starting at 11am. Admission for participating adults and over-5s will be just £7. Since 1997, the Big Toddle has raised £14.5 million. The event is marking its 20th anniversary this year by teaming up with Teletubbies, which is also celebrating its 20th anniversary.

The antics of Tinky Winky, Dipsy, Laa-Laa and Po have featured in more than 400 episodes of the popular TV programme and entertained children in more than 120 countries.

Barnardo’s regional director Hugh Sherriffe said: “A huge thank you to everyone who will be taking part in this year’s Big Toddles. Last year the events raised almost £600,000 which is helping to transform the lives of the most vulnerable children in the UK. I am excited Barnardo’s has teamed up with the Teletubbies, some of the most popular characters in TV history, for this year’s events.”
