Is coughing and sneezing normal for a 3 weeks old baby ? Should I bring her to a doctor ?

Sneezing is definitely normal. But I am it so sure about coughing? Does she sound like she has phlegm and was anyone else in the house sick recently?if she is coughing quite often and not the clear throat type I think it is better to bring her to see the PD. When they are so young they won't be given cough medicine but to be sure her lungs are clear do have the PD listen to her. My gal was born with a lot of phlegm since birth. Everyone including the polyclinic pd said at first it is saliva not phlegm. I listened to them because they are the professionals and more experienced than me. But after one month I listened to my mothers instinct and knew something wasn't right. Brought her to see PD and she was diagnosed with mild laryngomalacia ( a weak tissue at vocal chord) and what we always heard was phlegm. So my point is listen to your mother's instinct
