OMG! I just cannot believe it! My almost 3 year old has been on Singulair since the fall and was on it last year as well and she has been suffering with chronic otitis media, she was diagnosed with idiopathic hives, she has developed a patch of eczema on her leg, c/o stomach discomfort -- Needless to say I have discontinued this med. I am really upset over this! She has an ear recheck in 2 weeks because we are at the point where we are considering put tubes in her ears. I just cannot believe this! Gigi
