Hindi po blood ang orange stain, usually yan ay uric acid crystals o "brick dust" na normal sa babies, lalo na if hindi pa sila fully hydrated or nagpapamula lang ng urine sa diaper. But since she's 6 months na, best i-check mo pa rin with your pedia to make sure everything's okay, especially if it's persistent or may iba pang signs na off. A few of us mums naalarmed din dati sa ganitong kulay, pero okay lang naman sa dulo, mas importante lang na well-hydrated ang baby at normal ang feeding pattern.
