Aw, first-time mom worry talaga yan! Maraming babies ay may dark patches or uneven skin tone, lalo na sa forehead, kasi ng hormones from pregnancy or just genetics, madami sa amin may ganitong experience sa babies namin. Pero if it's spreading, hindi nagbabago, or may ibang symptoms, mas better na i-check ng doctor para sure at walang alalahanin ka, especially kung bago pa lang siya.
