Teething - such a tragedy. You're rolling around, exploring your hands, feet, and the world with your mouth, which is the center of your sensory world ... and wham. Sharp teeth start poking through. It just ain't right. And if adults had "teething", we'd all be popping Percocets. Not a safe choice for the wee babes, however ... so short of major narcotics, what's a parent to do?

I am also not a fan of teething gels - taste bad, numb the whole mouth, don't last long enough, and have the potential for allergic reactions. Stick with tylenol or ibuprofen, teething toys or frozen rags/bananas, and maybe Hyland's Teething Tablets if you like that naturopathic sort of thing (being in Seattle, we often do).
