My 3 yr neice was going through the same - apnea - snoring... First Dr (a surgeon) recommended removal of adenoids - no way! My sis did not want her child to go under the knife - drugs to put you asleep for surgery are toxic - requires homeopathis cleanse, etc.
So: Neice has had food sensitivity testing with a naturopath - cutting out all wheat, limiting dairy in diet. Also doing homeopathy for reaction to MMR shot she had a while back which worsened apnea symptoms. Sis is also giving her raw veg. juices (got a juicer on craigslist) as often as she wants.. Hope this helps!
