My baby breathes too fast. Always. Sometimes it’s not as fast as other times but if he is doing something it’s really fast, like he is panting. I don’t know what to do anymore. I have taken him to the doctor so many times and they look at him and say he’s fine. They listen to his chest and his heart and they say he seems happy so it’s probably nothing. But I’m sure it’s something. Does anyone else have any experience with chronic fast breathing? Is there any chance that it’s normal?
