I can understand your concern. You should immediately consult neonatologist and get done clinical examination of your child. This is not normal to have coughing and bleeding from nose and mouth. This can be life-threatening. There are many causes for this. Common causes are lung infection, pulmonary hemorrhage, bleeding disorder, coagulopathy etc. Your baby needs thorough clinical examination and investigations like blood reports, chest x-ray, x-ray of paranasal sinuses. So don't wait at home, rush to neonatologist. Hope I have solved your query. I will be happy to help you further. Wishing good health to your baby. Thanks. </s>
