Secret Life of 4, 5, 6 Year Olds

The four-year-olds take their first steps towards independence, learning about friendships and social interaction with all the ups, downs and humour that entails.

The children are back after a fortnight apart, but this time they are joined by some new faces. How will their friendships have developed, and will the new children stir up the playground?

Drawing on the experience of their first year at school, these five-year-old children have expanded their vocabularies, are learning how to make friends, and are beginning to get to grips with wider concepts like morality and identity.

The five-year-olds come back together after two weeks apart and are joined by some new playmates. Time has made the heart grow fonder, as Alfie and his best friend Emily reunite.

Articulate and sophisticated, the six-year-olds have had the benefit of two years at school and are beginning to focus much more on their own identity. Race, religion, love and death are all up for discussion.

The six-year-olds return after a two-week break, with some new faces joining the group. The sophistication of their language, their interactions and the impact of the outside world on their play and socialisation are ever more apparent.
