Ay, mama, kahit kailan ko nakikita yan sa baby ko medyo nag-aalala din ako kaya better check with your pediatrician about this one, maroon-ish spots in poop ay pwedeng normal depending sa diet niya (especially if may solid food na or kung breastfed lang), pero better safe than sorry talaga. Your baby's health is super important kaya peace of mind mo worth it ang checkup! You're doing great monitoring your baby closely like this, that's what good moms do.
