Hot lemonade soothes a tickly throat
Last night, my six year-old son was awake with a not-serious-but-constant hacking cough (from the sounds of it, similar to what Whiffleboy's daughter suffered with). The usual remedies weren't helping. In a fit of inspiration (or perhaps it was desperation), I fixed him a cup of hot lemonade -- a mixture of lemon juice, sugar, and hot water -- which he sucked down right away, and within 5 minutes, he was asleep. Nice Vitamin C hit, too.
