Ay mama, sakit mata kat baby 4 bulan tu memang kena jumpa doctor sebab mata dia masih sensitive, bukan boleh guess-guess. Doctor akan check dulu jenis infection apa (viral ke bacterial), baru decide pasal ubat titis atau tidak, some cases kena cleaning je or warm compress saja. A few of us mum friends kena situation mcm ni, and honestly better safe daripada sorry sebab mata baby boleh jadi serious kalau salah treatment. Go lah sooner rather than later, ya?
