my 2 month old baby boy has cold and cough. I cant see any mucus coming out from nose while he sneeze and he coughs more while he is crying. He sneeze and cough daily 4 to 5 times in a day. But I am so much worried about his breathing while sleeping. He is not able to breath properly becuase nose blockage(may be) while sleeping even after using nassal drops. breathing is normal when he wokeup and breastfeeding. Please advise
