Hi mama! Green poop tu actually normal for babies yang mixed feeding (BM + FM), especially dalam first few weeks, transitional stool kat babies memang boleh berubah warna depending on what they're digesting. Tapi kalau baby active, feeding well, dan tidak ada tanda-tanda lain macam perut kembung or feeding issues, biasanya okay lang. A few of my mum friends pun pernah experience yang sama, and their pediatrician cakap it's just part of the journey! Kalau rasa risau atau ada perubahan lain, better check with your doctor to be sure everything's fine, especially since she's still very young.
