Does the baby choke on saliva to cough to meet pneumonia

If your

baby's saliva does

not contain bacteria, just inhale a small amount of saliva, and the baby's body immunity is relatively high. In this case, saliva will be reflected through the baby's cough, generally will not get pneumonia. But if the baby's saliva contains bacteria, and inhale more saliva, the baby's body immunity is low, this may cause aspiration pneumonia.
