Bubble and Speak was founded in 2016 as a small charity organization, inspired by the example of the Maisons vertes set up by Françoise Dolto in France, with the aim of welcoming children up to four years of age and their parents or carers, using a psychoanalytic approach. The ‘Bubble’ in our name indicates an emphasis on playing and the universe of childhood, while the verb ‘speak’ stands for our intention to focus on free expression, speaking and listening. This article presents the project's origins and its core concept, as well as two of our main challenges: the question of the families’ financial contribution and the principle of anonymity in our work.
