Ear Infection - Part Mama

Lately I have been feeling under the weather, may have caught a bug that Grady brought home from preschool. I started feeling yucky on Friday and by Tuesday morning, I felt like hell. Kris came home to take care of me and I went to the doctor's today to get checked out. Whaddya know...I have an ear infection. My doctor said I most likely got it from Grady. Ear infections are contagious??
