Welcome to mamapedia!!
Congratulations on your new baby boy!!
i'm sorry you are going through this. My youngest son was born prematurely and with pneumonia. He too would have rapid breathing - we took him to a pulmonologist and had him evaluated. at that age - we had to give him breathing treatments through a face mask.
I would demand a pulmonologist and get to the bottom of it. Our pulmonologist did a blood test and a CT scan of his chest. I'd have to do some digging - but I'm pretty positive I could find the paperwork. There was something wrong - it was attributed to him having pneumonia but I do NOT remember what they said caused it.
I'm sorry - it's been 12 years - I don't remember what caused his erratic breathing. I just remember knowing it wasn't right. He is now 12 years old and strong and healthy!! We just kept pushing!!
Good luck!
