Hello girls, I have a question, how to drip the baby's nose when he has a runny nose? The doctor prescribed us saline solution to rinse the nose and Aqua Maris drops. But there haven't been any improvements. It's easier to breathe now, but the congestion is still there. (We've been dripping for two days).
