Poor baby and poor mama. Ds1 spiked a random fever after a normal day of play last year and it turned out he had roseola. Maybe it's that? Fingers crossed it stays down.
Glad his fever came down. When my DD battled a recurring fever it turned out to be Roseola. The fever was the only symptom, and it got as high as 104.3.
Yes, full doses. I usually try to stagger them in a way that they aren't wearing off at the same time (tylenol is 4-6 hours, motrin is 6-8, so I usually start with motrin and 4 hours later give Tylenol, then 2-3 hours later give Motrin...). But with a 104+ fever I'd be freaking out and do full doses of each immediately.
This is good to know! I knew I could stagger them so they overlap but I never would have thought I could do both at once and it's really good to know I can do this if she ever spikes a fever that high!
