Ray, my DD tended to suffer like this as she has inherited my tiny narrow eustacian tubes (I had grommets as a child but not before being terribly ill for months). She would either get an ear infection, tonsilitis or conjunctivitis (usually a combination of two of the above). We have found that the colourfree Dimetapp is a godsend, it tends to keep the conjestion down and therefore the bacteria doesn't get a chance to brew. I start her on it now whenever she has so much as a sniffle.

Hope this helps.
