For professionals trained at CESI


The main mission of the Center for the Study of Children's Sleep (CESI) is the training of health and education professionals capable of treating children's sleep problems with a respectful approach to the needs of the child according to their stage of development.

The CESI does not promote cognitive behavioral techniques designed to impose solitary sleep based on letting them cry (Crying it out, Controlled crying, and Camping out) or any training method that encourages letting the child cry without an active attempt from the caregiver to comfort the child. These techniques are incompatible with CESI's philosophy.

With the aim of providing clarity to consulting families and safeguarding the prestige of the Center for Infant Sleep Studies and that of related professionals, the CESI Code of Ethics details the commitments assumed by the professionals attached to its network:

  • With the baby

  • With the families
