I stuck her in the van and headed off to the ER (celticdragonfly stayed home with Jamie, who was sleeping peacefully). Blasting the A/C in the car made a difference, she was coughing much less by the time we got there. She was still feeling very sick. The triage nurse got no cooperation at all from her.
The nurses gave her some ibuprofen and a pile of stickers to play with. She did better as time went by. The doctor examined her (stethescopes tickle) and declared it to be croup, but wanted her x-rayed to be sure it wasn't pneumonia. I questioned that, mostly because I didn't think the improvement in her odds of having a subtle disease didn't outweigh the increased odds of me getting her killed in a car accident by falling asleep on the road. But he insisted and it only took an hour of waiting to get the ten minutes with the tech. So we were home by 3am.
celticdragonfly gave her some steam time in the bath this morning to keep the system clear. So now she's just at the sick-and-tired lying under a blanket stage. Which I'm glad to see.
