Good morning everyone!!! It's been two months already, we've been coughing since birth, I told you about it now, a cough has started, not much of anything, I'm afraid ? because we're still little, there's no fever or weakness, that's normal! What can be done? The pediatrician says it's normal, supposedly the child's lungs should work if there's no fever, weakness, then it's fine.
