A cough is a necessary evil. It can be annoying and uncomfortable and when it lingers it can become troubling. It's especially hard as a parent when your child is continuously coughing, and you just want them to feel better fast. Coughing is our body’s way of moving mucus and foreign substances out of the lungs and respiratory tract. It is a powerful source of protection for the body but when it lingers for weeks and weeks, a cough can be a real pain. You can help to shorten the duration of a cough by taking action to remove excess mucus from your system. Babies need special help riding mucus as they are unable to blow their nose or take certain medications.
