The Secret Life of 4, 5 and 6 Year Olds - Episode Guide

A group of four-year-olds meet for the first time and forge new friendships. Surprise visitors arrive - 10 eggs inside an incubator. The children watch in excitement as they hatch during the week.

The series that lifts the lid on the uncensored drama of life in the playground returns, with more cameras than ever before and a brand new inner-city school. In the second episode, the four-year-olds are back but this time they're joined by some new faces. The week starts off with a bang as new girl Milana clashes with last week's alpha girl Evie-Rae. Tensions continue to rise and sparks fly as the girls are teamed together for a building task. Milana's play style threatens to alienate her completely from the group, until she hatches a smart plan to turn it all around. As the children wrestle with finding their place in the group, this week sees just how important language skills and assertiveness can be with four years old. Verbally dexterous Enzo continues to take a leading role and as new boy Kahana struggles to find his voice, a temptation task offers him the chance to shine.

Ten new five-year-olds arrive at the play centre. With a year of school under their belts, these children are asserting their independence and becoming more and more interested in exploring the adult world around them. How do they cope when they meet other children who are different to themselves? Confident and charismatic Jude quickly takes on a dominant role within the group and it's not long before romance starts to blossom between him and Ellie. But their relationship is put to the test when they're given the grown-up responsibility of looking after a crying, life-like baby. Meanwhile Daisy, who has cerebral palsy, is limited in her ability to physically play with the other kids in the playground.

In the final episode of the series, the five-year-olds are joined by some new faces. Competition is something we often want to shield children from but it's an integral part of every five-year-old's life. How will they cope with winning and losing when they're challenged to compete against each other? Sensitive new boy Nat has never won a trophy. As he vies for the attention of fellow new girl Calla and his losses mount across the week, what does he learn from his defeats? Meanwhile, confident home-schooled Calla faces a bravery test and takes the lead in repairing the girl's relationships, as a fall-out threatens to end their friendship. Football ace Jet shows her true colours as she offers words of wisdom to her teammates and shows how winning can be fun. The children wrestle with the complex human emotions that succeeding or failing engender in all of us, demonstrating that competitiveness is not a negative trait and that learning to win or lose gracefully takes practice.
