What is the best remedy or relief for prickly heat? I searched it and was recommended to remove clothing from rash area but it's icy cold over here I can't possibly let son go around topless in freezing temperatures. My son is almost a year old and has prickly heat rash on his back and the back of his arms. I've let him wear 2 clothing layers (light fleecy l/s sweatpea + Grobag 2.5) instead of 3 (+ cotton thermal PJ) overnight since I discovered his rash but his hands are clammier. He used to sleep through the night with absolutely no problems but for a week now he wakes up several times yelling. I'm sure it's not due to teething because he's writhing on his back like he's trying to have it scratched. I used to have prickly heat as a teen and it was absolutely painful I can imagine his suffering. Any help would be much appreciated thanks!
