Liam had
meningitis.

He had flushed cheeks and felt feverish, but something seemed "off" so after a general doctor's visit, we went to the ER with a temperature of 101.4.
Urine, blood, and spinal tap tests were taken (NEVER want to go through that again, even if he never remembers any of it!) which sent us to the pediatric unit of the hospital.
Fortunately it was caught early enough that we were only there for a few days. I thanked the staff for doing such a great job, but told them I hope I never have to see them again.
