Don't know if I'm missing obv signs of illness, but ds (4 yrs) has had 2 nights of being v hot to touch (no temperature), then day 3 developed weird speckles on arms that turned into red arms like sunburn, that went overnight, then hoarse on days 3/4, now day 5 and last night had bad cough. Meanly sent him to school, though tired, as is still being a boy and annoying siblings. Am I being thick and missing something everyone would know about?
