The Secret Life of 4, 5 and 6 Year Olds (2015) IMDb
Seen in 2017.
This review refers to all 6 episodes of the 2015 “series” of this recurring Channel 4 program, the actual title of which is unclear.
In each pair of episodes, about 10 children aged 4, 5 and 6 respectively are sent by their parents to spend a couple of weeks at a special daycare center rigged with cameras. Teachers arrange psychological experiments on them and experts in child development observe the results.
Adorable and instructive, particularly the younger children, but the reality-TV tropes (confinement, Big Brother-style total surveillance, absurd challenges to provoke drama, focus on a few colourful characters, parents horny for stardom) overpower the scientific content.
