Eh sayang, kuning baby kat 16 hari tu memang kena ambil serius, please go to clinic or hospital right away, ok? Doctor kena check bilirubin level dia and tengok treatment apa yang baby kailah. Jangan delay, lepas-lepas boleh jadi complicated. Lepas doctor check and guide, then barulah kita tahu apa next steps (phototherapy atau apa). Dah tanya pediatrician dulu belum? Kita tunggu doctor punya advice je sebab ni kena proper monitoring. Sending hugs, will be ok!
