Como Say What?

Joshua has a unique, two-toned cry. It is like his cry is hitting two different notes at the same time. Well, the pediatrician suggested Joshua see a Specialist. Today was the day to see the specialist. They put a scope through his nose to look at his throat. Oh my! Poor little Joshua. Good thing he is too young to be permanently mentally damaged for life! The Doc didn't see anything constricting his airway or anything serious. Phew! But he did say he saw some mucous and some, as he phrased it, "screamers callous". He says you see it mostly in 2 year olds from screaming and in singers. Okay, so how does a newborn have something like this??? He said that it could have just been the mucous broken up instead of callouses. Ok. Basically it is nothing to worry about and is nothing serious and will go away. They want to see him again in 4 months just to make sure all is well. So, curious as I was about what he said, I came home and looked up "screamers callous" on the internet and found absolutely nothing! I tried to find something about his unusual cry and found nothing! So what is it??? Did the Specialist have his own lingo? While I do appreciate them and the work they did for my sweet little baby, I can't help but say...."Como, say what???" So my question is.......has anyone heard of this before?? Or does our Joshua have some completely rare, but actually cool cry? Oh baby Joshua we love you and your two-toned cry! And your daddy is right, you are going to make an awesome lead singer when you are older!
