question: My 6yo son has,multiple seasonal and environmental allergies along with peanut and tree nut allergies. Over the last 3 months he has had what they are saying it is acute spamsmotic croup and are sending him to a pediatric pulmonaligist next qeek. He gets it anytime hes sick even a simple cold. He coughs so hard tjat he drools and has the retractions and stiridor and tjat xan last for 2 hours at a time. Im just curious on why it happens i thought he was passed the age for croup. And am wondering if it would be smart to get an o2 sensor
