Aduh, phlegm yang pekat memang leceh lah, auntie understand! Kalau baby baru 17 hari and berkahak macam tu, better check with paediatrician or nurse cepat-cepat ya, especially if dia struggle to feed or breathing nampak susah sikit, sebab bayi baru kena monitor closely. A few of us had baby with similar issue, and most of us ended up pergi clinic untuk suction dan check if ada infection ke apa. In the meantime, make sure dia feeding well and monitor temperature, okay? Jangan delay lah dengan newborn, better safe than sorry!
