Talk to Pulmonologist / Lung on I Think My Daughter Has Chest Congestion

My daughter was born prematurely. She was born at the beginning of the ninth month. She is ten days old now. She was perfectly fine when she was born. She is still perfectly fine, but there is a sound in her chest.When she breathes, the sound comes from her nose and she breathes by blowing her nose. This problem is getting worse today Sneezing a lot.. I have also had it nebulized and nasal drops put in the nose.
