The award-winning Channel 4 series is returning to follow 4 and 5 year olds, as they play, learn and interact with other children in a nursery.
Children will be observed throughout by leading scientists and psychologists, who will give insights into child development.
The show is currently looking for 4 and 5-year-old children and their parents to take part. Your child would be needed for a week or two of filming during the summer holidays.
