Hi K.,
Our 5 year old, as an infant and toddler had horrible times breathing. It was so noisy just when he was breathing regularly. I discovered when he was 2 that he quit breathing when he was sleeping. It ended up being obstructive sleep apnea that he was diagnosed with. I firmly believe that is why he didn't have a "normal" sleep pattern in infancy and as a toddler. He woke up every 45 minutes or so.
If your son's sleeping isn't interrupted and he isn't cranky during the day, then I would wait. He may need to have an aneoidectomy and coblation of the tonsils like my son had. If his sleep pattern is not good, I would get a second opinion.
And, I didn't realize that my son couldn't "smell" either (made sense after the operation). After his operation, he would take everything he could get his hands on and smell it. It was adorable and so sad at the same time.
Good luck to you.
