Mama, please bring baby to the doctor right away or go to the nearest clinic/hospital to check this, blood sa poop ay kailangan tingnan ng professional agad, especially sa ganitong edad. Don't panic, pero ito hindi dapat i-wait, okay? Maraming possible reasons, pero kailangan ng doctor para malaman kung ano talaga at alagaan properly ang baby mo.
Thinking of you, malakas ka yan!
