When my girl is “talking” or whining/fussing she sometimes is making this wheezing sound, she isn’t coughing, no runny/stuffy nose and my SO and I can’t figure out if she just realized this is a new sound she can make or if it’s some sort of chest cold/lung problem.. We’ve been staying with my mom who is a nurse due to gas heat outage in our town and she seemed a little concerned so she listened to her lungs and said it seems to be coming from her diaphragm.. is this worth a trip to the doctor? Does anyone else’s baby do this?
