Well, we're back from the doctor. She mentioned that J's lungs are clear and he looks fine, but she was concerned about the coughing and prescribed an inhaler with an aerochamber for him. In a month, we're going to go back, and if his cough is still there, we'll look further into the issue. If it's caused by asthma or allergies, the inhaler should show a huge difference within a week.
So mama and baby are both on inhalers now (sigh). I was hoping to not pass on respiratory problems to him, but what can you do, right? Hopefully it's something just brought on by a cold, or maybe he's got seasonal allergies?
