DS has a recurring rash on his bum and round his hips and outer tops of thighs. It is raised red spots, which sometimes come to a head like acne, and sometimes not, and they all seem to have a quite wide white "halo" round them.
He's been toiler trained for a few months now, and I did thin it was to do with when he had an accident and got urine on his skin, but it's not happening in the places he's actually wet.
Any ideas ?
