How do I treat prickly heat on a 1yr old's body? :(

Here's what u could do: Use a mild soap and tepid water during bath time to help soothe his skin, then gently pat skin dry. Keep affected skin dry. If it’s extra hot, use a fan to help wick away sweat. Skip powders, oils and lotions, which will only make the rash worse by further blocking the pores. Let baby take a naked stroll or crawl around the house.
