Presenter, paediatrician Dr Guddi Singh chats to several scientists as they set babies various tasks and challenges and interpret the results. The experiments are interesting, but also quite fun to watch.

In the first one, Dr Emily Jones wonders if it’s possible to spot a baby’s temperament at just six months old. Putting them in front of a Jack in the Box, a toy dog that suddenly somersaults and then a person in a clown mask, some are excited, some calm, while others are cautious.
