Ay, green poop with mucus-like stuff can be normal sometimes, lalo na kung exclusive breastfeeding pa lang or may lactose imbalance, pero kung parang may sipon na appearance at malagkit talaga, better to check with your pedia, a few of us moms noticed na ganyan ang poop ng babies namin when may slight tummy upset or pagbabago sa milk, pero 3 months pa lang si baby mo kaya mas safe na i-consult na lang. Keep an eye din on kung may other signs like fever, irritability, or if baby seems uncomfortable, kasi sometimes that greenish mucus-y poop can also mean something needs checking out.
