Congested 3 week old

Jazmyn

Does anyone else have a congested babe? My poor girl, it sounds like she’s having a hard time breathing sometimes. Mostly at night. I went and got a nosefrida and it helps some but I feel like it’s in her throat too and I feel so terrible. Her pediatrician really didn’t say much except I could get her tested for Covid but I don’t want to do that because I doubt that’s what it is. I think it’s just a cold. What can I do to help her?
