Ok, I actually have no idea if this is common or not, buuuut I found it really strange that DD's new pediatrician ordered a lung x-ray for what turned out to be a standard cold. And that he ordered antibiotics for her as well. These are two firsts for us, and DD is 3.5.
I spent all last night panicking and frantically reading about pneumonia on line, then I got to the radiology clinic today and the waiting room was full to the brim with runny-nosed, coughing kids. A quick convo with one friend here revealed that it's pretty standard at the height of flu season to send sick kids for xrays and prescribe antibiotics.
I don't plan to write a book about this difference in the "French" way of raising kids, but I did feel like I needed to share it with someone.
ETA: DD's xray revealed her lungs were completely normal.
