Whether sneezing is normal in newborns also depends on the circumstances. If sneezing occurs occasionally, it is mostly normal. However, if the sneezing is frequent and severe, it should be considered abnormal. Occasional sneezing in newborns is mostly related to poor indoor air quality, such as too much dust, too cold or too hot air, and some irritating odors, which can cause physiological sneezing in infants. However, if sneezing is more frequent, especially when accompanied by nasal congestion, runny nose and phlegm sound in the throat, we should consider that sneezing is related to upper respiratory tract infection. If there is fever when measuring the body temperature, effective measures must be taken in time to control the rise of body temperature to avoid high fever. Newborns are more sensitive to the external environment due to poor thermoregulation and are prone to catching cold, so it is important to keep warm and increase or decrease clothing according to the weather and indoor temperature. When sweating too much, you should wipe the sweat in time, and change dry diapers or diapers as soon as possible when there is excretion to avoid catching a cold as a result.
