DS was off color yesterday, easily upset and quite hot to touch but seemed fine this morning, good appetite and cheery so sent him off to school. On pick up they said he had been really quiet today and when we got home he started crying because he had felt really cold today (although he perked up after some hot chocolate!) He has pink/red cheeks and noticeable lymph nodes in his neck, so I'm not sure whether to send him to school tomorrow or whether to take him to the doctors to be checked out?
