Aw, I feel you, baby cough is the worst! A few of us moms swear by doing a gentle chest and back massage with warm coconut oil or eucalyptus-based rub, lalo na before bedtime para makatulog ng maayos, and I always make sure the room is humid by using a humidifier or even just putting a basin of hot water nearby. Pero honestly, if the cough persists or baby has fever, best to check with your pedia para sure it's not something serious, better safe than sorry talaga with our babies!
