extra skin attached to back of tongue

My son is 13mos. He has "low muscle tone". We do not know why. We just noticed an extra flap of skin attached to his tongue. It looks like a tiny mini tongue. When you look into his throat you do not see it. When he coughs it comes up and forward. It curls just like his tongue. It is attached to the base of his tongue in the back of his throat/mouth. Someone mentioned it his epiglottis or a lesion/cyst/tumor. What is it? What is the name of the disorder? Why does he have it? Thank you so much for your info. Teiko.

It is tough to make an assessment of what your son has without actually examining him.  The best recommendation is to have your patient seen by his physician.  Make sure you share your concerns and show the doctor exactly what you are concerned about.  Best wishes.
