We live in southern California. We as a family have gone for a vacation to Florida last weekend. My toddler is now 28 months. He had no allergies from birth. But after coming from vacation, I've noticed few red patches or rashes like on his lower rib part, within a day it is spreading. Now I can see the same in his chest, on his back and some on his face too. Is it any sun damage or any other allergic blisters. I'm not sure whether it is itchy...since he is not itching any part of the body. What kind of safety measures do we have to take, can I get the expert advice. Thanks in advance.
