Looking for suggestions-- my LO is almost 4 months. We've been battling a cold/cough for a little over a month now. He cannot shake his cough, mainly at night. We run a cool mist humidifier, do nasal drops, have a nebulizer, prop his head while he sleeps but he's still hacking up a lung. I'm running out of things to do and doctors don't do anything either. Recently he got put on a reflux medicine but after a week I've seen no improvement. It's frustrating 😞
