<unk>  occurs when the walls of the trachea collapse. This can happen because the walls of the windpipe are weak, or it can happen because something is pressing on it. This may include hypotonia of the trachealis muscle. The whole windpipe can be affected, or only a short piece of it. If the collapsed part of the windpipe goes past the area where the windpipe branches off into the two lungs, it is called bronchomalacia. This problem causes noisy or difficult breathing in the first 1 to 2 months after birth. This is called congenital<unk>  (it was present at birth). It is not very common. Babies born with<unk>  may have other health issues like a heart defect, reflux or developmental delay. Some children get<unk>  because of other health issues. Symptoms can be mild to severe. Symptoms inside the lung include noisy breathing that may get better when you change your baby's position or while he or she is asleep. Breathing problems that get worse during coughing, crying, feeding or colds. High-pitched sound during breathing (stridor). High-pitched cough. Rattling noise or wheezing with breathing.
