M.H.
I am sorry, but it sounds like the school is not so clean or they are not following guide lines with washing their hands and toys. My son had same issues with ear infections and colds since he started daycare in September. Just colds and he would develope the ear infections because of them. We just this pass week had tubes put in his ears. He could hear so well now, and he is much happier. We did not even know there was a hearing problem since he spoke well for his age. Apparently this was going on we did not know it. You want to see an ear, nose and throat doctor for advice. Good Luck! :)
