Update

I think I spoke too soon....Alyvia was doing alright, but then yesterday she got really sick and had a fever all day. She was having a really hard time breathing (I was so worried she was getting pneumonia.) We had to take her back to the pediatrician last night. He was worried about her lungs, so Livie had some chest X-rays to see what her lungs looked like.....
They looked good!! PHEW! I was SO relieved. She doesn't have any fluid in her lungs and the atalectisis (portion of lungs that has closed off) has even gotten better.
Because she is having such a hard time breathing though, she is starting a steroid, the albuterol treatments just weren't cutting it. I am not crazy about a steroid, but it's a low dose and if it helps her breathe than it's worth it.

The pediatrician thinks the most likely cause of the new fever is a viral infection on top of what she already has (RSV.) The doctor doesn't want Livie on antibiotics because of her long history with C-Diff.
Right now our biggest concern is Alyvia's lungs and making sure she is getting enough oxygen. As long as her lungs can hold up she'll be okay, and right now they are. (They just better keep holding up!! ;)
