Eh susah nak tahu dari jauh saje mummy, bintik-bintik kat pipi baby boleh jadi banyak penyebab, ruam, alergi susu, atau juga heat rash je kalau cuaca panas. I'd really suggest you snap a photo and show your paediatrician because they boleh confirm properly, especially kalau anak minum formula, they'll know terus if it's milk allergy or something else. Meantime, jangan kucuk-kucuk area tu and keep it clean and dry, okay?
