Girls, yesterday I wrote about teeth...Temperature rose to 39 at night, twice a night I lowered it, down to 37.8 and then it rises again...I gave him ibuprofen, candles Cefecon once, wiped him down and drank plenty of water. Now I woke up and it's burning again, being fussy, gave him a child's tooth brush (silicone teething ring), he only gnaws on it like that (calmed down a bit), how can I further ease the little one's condition? I haven't slept for 3 hours since last night.
