DS is 12 months. Fine all day but didn't eat his tea, very unusual. Put him to bed at 6pm as I thought he was overtired and noticed he seemed a bit warm and his hands were shaking. This stopped after his milk so wondered if it was blood sugar/hunger making his hands shake. Took ages to go to sleep, no crying just whimpering. 8.30 his temp was 39.8 so gave him calpol. Midnight violently sick everywhere, gave him water and stripped the bed and he went back down. 1.30am more sick and temp 39.9. Don't know what to do. DH abroad and DD 2.8 asleep. I'm panicking he's getting hotter.
