A prickly rash appeared on my DS (1yo) legs overnight, it’s got worse throughout the day and now is on his knees, bum, willy area and behind his knees.
I can’t think what it could be - It faded under a glass however. He’s had a cold for around 5 days but I’m pretty sure that’s unconnected.
He doesn’t seem in any pain or particularly bothered by it.
