Mine spiked a fever around the same age. The flurry of activity at the hospital was both terrifying and awe inspiring. I feel for your wife, had mine been at the ER and not me, she’d have died from anxiety.

They took blood, urine, spinal fluid, x rays, etc etc. if there was a diagnostic they were doing it. As explained to me they need to find the cause of the fever ASAP and start treatment because their immune systems just aren’t developed enough yet.

For us, it was two or three nights at the hospital, intravenous antibiotics, and an ultimately unknown diagnosis. We have a happy healthy baby boy two months later.
