I would get a second opinion from another ENT!!!! Three seems very young to have that procedure done!!! My son's pediatric ENT said they used to do them all the time (like our generation and before), but now he only does them very, very sparingly and when they are completely necessary, based on observations over at least a year's time of things like recurring or hard to get rid of strep throat. I'm curious what is going on that he thinks it's necessary to operate on a toddler, whether full or partial! Also, that same ENT said when he does the surgery on tonsils, he usually removes the adnoids, too--- what did your ENT say about that???? I would do more research and for sure get a second opinion!!
