Aduh, 4 hari memang agak lama lah, especially kalau baby baru, better to check with your paediatrician cepat je sebab dia boleh tengok baby directly dan assess betul-betul. Tapi good sign la perut dia tak kembung and he's passing gas, which means ada movement dalam digestive system dia. Since intake FM dia very low tu, maybe latch issue ke or dia prefer breastfeeding more, doctor boleh help sort this out and make sure he's getting enough overall. Hang in there, mama!
