Ehhh, bintik putih kat leher baby yang baru lahir tu memang common! Anak saya dulu ada jugak, most of the time it's just milk residue atau heat rash sebab babies sweat kat leher area tu, lagi-lagi kalau weather panas atau dia pakai baju tebal. A few of us mums dalam my group tried gentle warm water baths dan make sure leher dia stay dry, especially between the folds, and it cleared up sendiri dalam seminggu atau dua. But kalau the spots are spreading, panas, or baby seems uncomfortable, do have your pediatrician check it out just to be safe, better to rule out anything else!
