Taking premature babies out of the incubator and placing them skin-to-skin with their parents is a sensitive time for them, and a source of stress for parents and caregivers. But this care is essential for the baby's development. With this in mind, we have designed and developed the Cocon Douceur. It has been evaluated in terms of the child, the organization of care and the satisfaction of parents and caregivers. The results obtained are positive in terms of the toddler's motor skills, improved comfort and easier care, with less handling by the caregiver.
