Syndrome unknown but more and more frequent, it can occur during a game (we throw the baby in the air for example) or during attempts to calm him down. With serious consequences: the brain manhandled by these vibrations comes to touch the wall of the skull and may cause brain damage.
If your baby vomits, convulses, has a disturbance of consciousness, take him to the nearest emergency department. In this area, nothing beats prevention. Wait for your child to be taller to heckle and if you can not stand his screams, call someone around you for help.
