DS1 went blue, face and arms, around 6pm and was shivering. He'd been playing in the garden with a vest, shirt jeans socks and shoes on. I'd say borderline whether he should have had a coat on - we'd just got back from a walk and he'd asked for it off. He was out for about 10 mins. My mum noticed the blueness when she read him a story when he came in for a cuddle.
Now he appears to have a fever - 38.7 from under his arm. Have given calpol but not sure if I should do anything else. Aside from these symptoms he doesn't appear unwell IYSWIM.
Anxious mother here, sorry, but can you reassure me?
