Diddi Dance classes in Twickenham, Teddington, Hampton and St Margarets joined a national campaign to fight cancer last month.
More than 2,000 toddlers put on their dancing shoes as the classes join up with Macmillan Cancer Support in aid of the charity's Dress Up and Dance campaign.
Founded by professional dancer Anne-Marie Martin, Diddi Dance provides a fun way to get toddlers on their feet.
She said: "We are so proud and excited to be involved in Macmillan’s fantastic Dress Up And Dance campaign, it is a natural fit with our weekly dance classes."
