RDF Television are making a brand new series of The Secret Lives of 4 and 5 Year Olds.

The series follows children as they take their first steps towards independence. It will follow their development from the moment they meet for the first time; through their forming of friendships; and the learning of social rituals and friendly competition. The entire process will be observed and monitored by leading scientists and child psychologists, who will provide occasional comments on the children's stages of development.
