Chronic ear infections are a possible sign of dairy allergies. If you google it, you will notice some great info on it. Also a good round of probiotics will help rebuild her immune system so she can fight off illnesses. When you take antibiotics it kills the bad and good bacteria making us more proned to the same illness and more. A sign of a weakened immune system is getting sick more than 3 times in one year. Renew Life has wonderful probiotics for infants/toddlers/kids. www.renewlife.com and you can find a store near you to purchase or go on line at www.smartbomb.com
A large study done proved that antibiotics does not work for ear infections, it just weakened the immune system.
Good luck!
