Aww, kesian baby batuk, I know how stressful itu kan! The best thing is to keep baby hydrated (minum banyak air or breast milk/formula), make sure the room air lembab dengan humidifier or tapi jangan lupa cuci regularly, and elevate baby's head sikit bila tidur, a few of my mum friends swear this helps tengok improvement dalam 2-3 days. But honestly, kalau batuk tu tak hilang or baby seems unwell, kena jumpa doctor cepat-cepat sebab ada babies yang batuk boleh jadi signs of something yang kena monitor.
