Ay, ang poop ng mixed feed babies talaga ay pwedeng mag-vary, kaya normal lang yan! Since combination ng formula at breast milk sya, you might see different colors and consistency, sometimes yellowish, sometimes greenish or brownish, and the texture can range from pasty to a bit more solid compared sa purely breastfed babies, so don't worry too much. That said, if you're noticing anything unusual like red streaks, mucus, or very watery (like diarrhea talaga), or kung constipated lang sya and struggling, better check with your pedia just to be safe, one of my mum friends said mas peace of mind lang knowing everything's okay sa doctor, especially pag first time parent ka pa lang!
