My son is breathing heavy and it scares me. He's gotten a cold that my niece and nephew had when they came down and still have. So I know he can't breathe that good from it but he's also hot. Just his stomach and back is. And he woke up awhile ago saying his belly hurt. I pray he doesn't get that virus back again cause it's passing along slowly to every single person in my house smh.
