So Dovi slept well over night.
Woke up at 6ish, having gotten meds at 4:30 am.
Went back into crisis at 7 am and had a fever of 102.
Gave 3 mg ibuprofen and 4 mg valium.
Better by 9am.
Took him to the pediatrician. Everything negative.
He seems to be somewhat fine now.
Thanks everyone for your good wishes.
Never, ever have we had to give Dovi four does of valium in 24 hours. Never.
