At bathtime DS (15 months) had a strong pink blotchy rash on his chest. I put a glass on it and it did seem to fade. He had a high temperature and was put to bed with Calpol. He went to sleep ok but did not eat any dinner and was obviously unwell. WWYD in this situation? Check on him when you went to bed? Or beforehand? Or just chill out a bit? He's my PFB and I'm not sure how much I should worry...
