Lots of good advise out there. The garlic is a good alternative as is the salt ball. Be very care about heating it, as salt can absorb a lot more heat that you think. I have been fairly scorched by it. I would try the decongestant as well. But, as a preventative, I would jack up the head of the kid's bed. They will not notice a 2 inch rise, but it can make all the difference in drainage of the ears. Neither of my boys ever had an earache and I am convinced this was at least part of the reason. Good luck.
