Dawn literally called two minutes after we got home. I just got off the phone with her, and I can reassure you that Caroline is going to be fine, but she's still in the hospital until an official diagnosis can be made.
All signs are pointing to a severe case of reflux. Most likely she will be put on medicine, but there's still a chance for a PH probe. The poor baby has undergone a spinal tap, EEG, cat scan, and several other tests, but thankfully all of them show everything is normal (no brain damage from lack of oxygen, etc.)
They are still waiting for some other 48 hour test results to come back, but they think Caroline will be discharged tomorrow.
Meanwhile, Dawn's blood pressure has never gone down, and obviously it was through the roof yesterday, so she was prescribed her own medicine yesterday. She will be haunted by Caroline's limp, blue body for a long time.
Please keep all of them in your prayers. If you would like Dawn's address to send her a note, please PM me.
