Children use a substantial part of the day to play. Play is not only fun, but also important for children’s development in many ways. December 12, Carolien was a guest at the ‘Kennis café’ in the Balie in Amsterdam, which is organized monthly in collaboration with KNAW, the Volkskrant, and science museum NEMO. After an opening in which a columnist expressed his antipathy for playing, the discussion with the four invited guests concentrated on the importance of play, the role of the toy industry on gender stereotyping, gaming, and new developments in play research. The evening can be followed (in Dutch) through this link.
