My son had constant ear infections early on. It came upon around teething, colds or whatever as fluid would trap in his ear canals and cause infections. We had tubes put in at 2 1/2 and it was a miracle worker The rule of thumb from my Pediatrician was if the ear ache is so painful it causes a lot of sleep disruption (and tylenol did not help) or causes a fever that lasts more then 48 hours (higher then 101) then to bring them in. Chronic ear infections are due to something not working right in their ear canal and tubes could help big time. If you know what you are looking for and how to determine if it is serious that is great that they have something out there to help moms determine that! :)
