My two year old has asthma...has not been on symbicort, but was on singulair daily for awhile. We have been giving her quercetin, fish oil, a multi vitamin, and acidophilus almost every day and she is doing much better and has been able to ween off of her singulair. Praise the Lord for His provision. For awhile she was on steroids almost every 4-6 weeks. It was very scary. She also does use an albuterol nebulizer if she has an attack. Just my $.02. Oh, and we give elder and rosehips most days too. Good for the immune system. Also, she had RSV at 11 months and then pertussis at 14 months. Used the cough tea from Bulk Herb Store, it really helps for congestion and cough's.
