Newborns with crying that causes poor vocalization and hoarseness can usually recover in about 3 days after active treatment. Vocal cords can be damaged after violent crying and acute inflammation of the pharynx, resulting in a mute voice. Parents should pay attention to soothing the newborn at this time, feed more warm water, keep the throat moist, and ensure that the child rests as much as possible, which can usually recover in about 3 days. However, if his voice is still hoarse for a longer period of time after treatment, other problems need to be considered, such as abnormalities in the congenital development of the vocal cords or larynx, upper respiratory tract infections, dehydration of the voice due to excessively dry air, etc. It is recommended to go to the pediatrician for examination in time to exclude pathological causes. Therefore, when a newborn baby cries, parents need to pay attention to calming him/her down, rule out the cause of crying, and on top of that, feed more water and ensure the humidity of the air to avoid dehydration of the affected child due to dry air, or even the situation of hoarseness of the voice.
