laryngomalacia

My baby was diagnosed with laryngomalacia at her 1 month old appointment. Has anyone else’s baby had this? Although the doctor didn’t make it seem like it was a big deal because it isn’t affecting her feeding and weight. And is apparently just some thing some babies have. It still scared the heck out of me me the weird breathing sounds she makes, I wasn’t given much advice on what to do for it, as it is something they made seem normal that resolves itself eventually. If anyone else’s baby had or has this what did you do for it to ease your mind and help your baby?
