Son has had a red, blotchy rash since Friday night. He's not ill, no temperature - mostly on his face, arms,legs and bottom - nothing on his tummy. I suspect that it may be slapped cheek, although am basing that on google images. AIBU not to sit for hours at OOH today (as my MIL thinks that I should) given that he's not in the slightest bit unwell or am I being a bad mother to not take him?
