The child is also moved by the movement of the mother or father. Here, too, the child's motor skills are stimulated by being carried in the sling. The movement causes the child to actively move in the opposite direction, which also has a positive effect on the child's muscles.
Movement helps the nerve cells in the brain to form connections with other nerve cells. These connections (synapses) are the prerequisite for learning and lay the foundation for good mental development.
In the sling they experience the familiar feeling of being in a cave, which they already know from the womb, and close to the caregiver, the basic trust is strengthened and the missing weeks or months outside the womb are made up for. By being able to move freely with the premature baby in the sling, a good bond can be built up and the perhaps missing bonding after birth can be made up for.
