We call the parts of the programme where children appear on the Teletubbies' tummy screens the 'inserts'. We have a number of specialist insert directors working in different areas of the country who look out for children with a special interest or passion, no matter how simple, that they can demonstrate or 'tell' to the camera. For instance, one director encountered a child who loved washing up. So she filmed the child washing up. The child's enthusiasm speaks for itself on camera. When we showed the insert to children they were absolutely riveted! Children do look forward to being on the programme. Filming can be hard work for very young children, so we do our best to make it fun.
