Salam! Describe abit more ya, is it merah2 aja or ada nanah, panas, or bau tertentu? Sebab ruam ada banyak jenis and treatment depends on what it is lah. A few of my mum friends kena heat rash or fungal infection, totally different creams needed. Better check dengan doctor first so dia confirm what type, then baru pakai the right cream, kalau salah cream, memang makin teruk je. Kesian anak kita kan
