If your newborn is spitting up bubbles, you can initially distinguish whether it is pneumonia or not based on some other accompanying symptoms. If it is accompanied by fever, cough, shortness of breath, etc., it may be related to pneumonia, on the other hand, if there are no other complications, it may be a normal spitting up of bubbles. Newborns who spit up bubbles need to be evaluated in conjunction with physical symptoms to determine if it is related to pneumonia, because pneumonia can occur with fever, cough, shortness of breath and other symptoms, and spitting up bubbles is only one of the symptoms. A comprehensive analysis is needed to determine whether other complications are present. If it is neonatal pneumonia, hospital radiographs can show a bit of flaky shadows in the lungs and so on. If the newborn spits up bubbles, there are no other complications, the spirit, diet, sleep and so on are normal, most of them are normal physiological phenomena. Suspected newborns have pneumonia, need to go to the hospital in time for relevant treatment, to avoid delay.
