My 8months Baby Sweats Excessively When Crying And Sometimes Holds

My 8months baby sweats excessively when crying and sometimes holds the back of her head. She is so used to me that leaving her for 2-3 min with another person brings about these excessive crying which in turn means excessive sweating... She has not been sick apart from from having colds and a fever maybe twice... Her growth is fine was weighing 9305kg and 75.5 in length, 43 head.. She eats well and breastfeed well.
