OH brought his LO home on Saturday night and told me once I had got home that he had/has chicken pox. By this point LO and my LO had already shared a bath together. My LO broke out in a red rash on Sunday morning (rash disappears under a tumbler) and still has the same rash this morning, mainly on her arms, legs and trunk and back of neck. She's not got a temp and is perfectly well in herself. She's so far not had chicken pox. Do you think it could just be a heat rash?? Or potentially the start of chicken pox? I've not changed anything or given her anything different to cause the rash so the only two factors are being round OHs LO or the heat.
