quote:" Buried in the news reports about the incident was the real answer to the whole conundrum: When the family boarded another plane the following day, little Elly was apparently smuggling a dose (or three) of Children’s Benadryl in her tummy. It’s the dirty little secret — one of them, anyway — for all sanity-seeking parents. If the kids are prone to episodes during high-stress times such as airline travel, dope ‘em.
Hey — we used to rub their gums with whiskey and stick thermometers up their (ahem) tushies, and those kids turned out, for the most part, just fine. Sometimes in this coddle-crazy world of knee pads, baby monitors and toilet locks, the old-school, tough-love methods are the only rational option."
