Ruam Di Pipi

Hi mommy My baby kerap sangat ruam dekat pipi. Mostly orang ckp ruam susu. Yes ada masa dia ok clear, ada masa dia jadi mcm teruk. I've been used sebamed. Tp this thing happen repeat again n again. Kesian dekat baby. Mmg dia tak meragam. Dalam masa pkp mcmni, should i bring my baby to specialist kulit? Or let pkp settle down baru bawak jumpa pakar...
