DS has what looks like lots of small insect bits on his torso - I.e. small raised centre with a larger redness around it IYSWIM. Could it be the beginning of chicken pox? It could be a reaction to something but it is now like a rash in that they don't seem connected to each other. He doesn't seem itchy but has been unsettled all afternoon but is teething his molars so not unsurprising. He is asleep now.
I realise this is quite hard to describe - tries to put it down as I visualise it!
