I don't really know what to make of this. A couple days ago JoJo started to do this thing with his breathing constantly. It sounds like he's trying to push air forcefully out of his nose, if that makes sense. It almost sounds like a human who has the sniffles, and keeps "sniffling" the snot back in, but it sounds like he's doing the opposite...where he's pushing it out. Could it be a cold? Allergies? I checked his nose, and there's no snot, or wetness.
Also (and this started at the same time as the "sniffles"), occasionally he'll do this rapid breathing sound, breathing in and out really fast, and it almost sounds like he's trying to clear phlegm out of his throat? But I don't hear any mucous or phlegm when he does it, so I'm not sure.
He's fine otherwise, still playful and full of energy. It's just that he's "sniffling" all day, and doing that strange breathing sound.
