my baby shaking hand leg and lips.. why do this.? am Very nervous plzz help me.. 1 month complete my baby

A. If there is a slight tremor primarily in the areas of legs, chin and lips and it occurs at a certain rhythm? Is this the case? The tremors or quivering continues for a few seconds and then stops. Such quivering exists primarily when the surrounding environment has changed its temperature or the baby is hungry or irritated. This can be due to a nervous system that is yet to develop fully. These symptoms usually fade away in a few months after birth. But please contact your doctor just to be sure.
