Newborn breathing..

Sara

My baby girl is 3 weeks old & she's making wheezing noises when she breathes, it freaks me out cuz it sounds like she's having difficulty breathing? How could I tell if she really is or if it's just me worrying to much.. I've took her to the doctor & they said she's fine but it's continuously happening... I wish I could post a video of how she sounds but I can't cuz that will be a better explanation 😫😫😭😭 any help or advise will be great! My first never sounded the way she does I just don't want something to happen to her but also can't be taking her to the doctor every single day...
