The key difference was professionally photographing each child who attended, with parental consent. The photograph was later mailed to their home with a letter and snacking sticker calendar. Children who completed the calendar, by replacing an unhealthy snack with a healthy one each day, were mailed a wipe- clean table mat as a reward. Their parents or carers were also entered into 2 prize draws (top prize £1,000 Co-op travel vouchers and a fruit hamper). They also received other communications, such as a recipe for a fruit snack. Each family received a "goodie bag" as they left the event, which included the book and plastic snack bowl, a Healthy Start leaflet, a piece of fruit, a Snack Right leaflet and any relevant local information from the children's centre or PCT.
