Hi all. My 7 month old boy has suddenly developed this rash. This morning it was just on on his chest but this evening it had spread around his side and half way across his back. Both me, his dad and older brother have issues with our skin but this came on so suddenly I am concerned. I would normally take him to the doctors first thing tomorrow but as its Saturday tomorrow I can't and I don't want to waste an out of hours call out if it's not necessary. Maybe a trip to the drop in centre? Anyone seen anything like this before? Thanks in advance :-)
