Loosely translated, KISS means ‘Disorders in the symmetrical development of the baby due to functional disorders in the upper neck joints’. The joints and muscles between the head and the three upper vertebrae play a major role in the development of the baby’s mobility and balance. The theory is that during childbirth there may be a limitation in those high vertebrae, so that the child cannot move properly and experiences pain. The baby/child often tends to tilt or overstretch the head. KIDD syndrome is a similar picture, but is often seen in older children.
You could say that a child with KISS syndrome continuously has a stiff neck that generally does not completely goes away. You’ll see that the child develops a preference in terms of posture and avoids a certain posture. Because babies can only communicate primarily, they will cry to indicate that they do not feel comfortable. This is very disturbing for many parents and often leads to a lot of stress. Because it is very difficult for parents to help get their child out of its preferred position by themselves, professional help is needed.
