Ah mama, normal lang yan especially kung mixed feed pa, basta wag naman bleeding or sobrang maingay ang tummy niya, okay pa! The green poop usually comes from foremilk or kung mabilis ang digestion, kaya hindi ka mag-alala doon, pero if worried ka pa rin or kung may other signs like fussiness or poor weight gain, mas okay mag-check lang with your pedia para sure. A few of us moms sa group namin may similar experience with mixed feeding at sabi ng pedia namin normal lang yan sa transition period between breast at formula.
