When is enough, enough?

Cooper is still having sinus, congestion, asthma, whatever...problems. 2 twenty day sets of antibiotics and 2 antibiotic shots later...Cooper still has ear infections. They decided to give him another 2 shots and hopefully these will do the trick. He will be going to an Ear, Nose and Throat Doctor to possibly get some tubes soon.
But he is still a very happy boy through it all. His dad says that he is just very tough.
