Dear Debbie, Have you evaluated the baby's nasal passage? It may have been clear at the hospital with a delay of swelling ( from suction, ect.). I had a case similiar to this and it was only one narries that was blocked but it was preventing him from swallowing and breathing. About 5 days old he developed noisy breathing. Mom used saline drops and by the next week he was exclusively nursing. Good luck. Ann Perry RN IBCLC
