Newborns should not be shaken, especially not violently, as this increases the risk of fetal brain injury. The newborn’s tissues and organs are not yet well developed, plus the head is too large in proportion to the weight is not yet stable, the head may move more violently when shaking, thus damaging the weak neck connected to it. And the skull base of the newborn is relatively flat, the brain is shaken by external forces to move, the skull is relatively thin, fontanel is not completely closed, shaking is more likely to cross the narrow subarachnoid space and reach the brain caused by injury. Therefore, newborns should not be shaken, and should be treated gently, avoiding high-intensity passive activities to avoid adverse effects.
