For a baby admitted to the neonatology unit, the transition from the womb to the outside world is very big. A baby misses the safe and secure environment of the womb and faces negative stimuli that can be stressful, such as examinations or an IV. This stress can interfere with the baby's development. Therefore, babies in the neonatology unit receive developmentally appropriate care. In doing so, caregivers try to protect babies from stress and unnatural stimuli such as lots of light and noise.

In the Divi "developmental care", parents are explained what developmental care is and how they themselves can play a role in creating a safe environment for their baby, for example, by pouching.
